What this template is for

Once you own more than a handful of firearms, simple questions get hard to answer: which safe holds a given rifle, what a surplus carbine cost, when a pistol was last cleaned, which guns are out with a gunsmith. This template answers them with one record per firearm, covering what it is, where it came from, what condition it is in, where it is kept and what it is worth. The Receipt and Disposition tabs follow US conventions, with lists of US states and fields for license numbers. Collection data stays on your own computer or phone, and the app itself never connects to the internet and needs no account.

The Identification tab holds what tells one firearm apart from every other: "Manufacturer", "Importer", "Model", "Serial Number", "Type" and "Caliber Or Gauge", plus your own "Custom Tag". Together they name the item the way a collector would describe it, and they still work when a serial number is missing or worn. The Description tab holds condition, finish, headspace result, Curio and Relic status, stock or grip material, storage, provenance notes, dates and values, which are the details an insurer, appraiser or buyer asks about.

"Manufacturer", "Model", "Type" and "Caliber Or Gauge" arrive filled with hundreds of entries between them, and "Nationality", "Condition", "Metal Finish" and "Storage Location" are ready to use, so you pick a value instead of typing it. Consistent spelling means reports and filters group like items together. "Custom Tag", "Serial Number" and "Appraised By" start empty and fill with your own entries. A maker, model or caliber the lists lack is one typed entry away and is offered again on every later firearm.

What you can do with it

• Produce an insurance list of every firearm with "Manufacturer", "Model", "Serial Number", "Appraised Value", "Current Value" and "Insured Value", using "Date Appraised" and "Date Insured" to show how recent each figure is.
• Check where every piece is, from "Safe 1" to a gun out with a "Gunsmith", "On Loan" or on "Consignment", by filtering on "Storage Location" in a custom report, and keep any printed copy as secure as the guns.
• Keep a service history on the Maintenance tab, logging each "Operation" with a "Completion Date" and a "Next Due Date", so each firearm's record shows when its next service is planned.
• Show how original a surplus rifle is by pairing its "Condition" grade and "Metal Finish" with rebuild dates and replaced parts in "Condition Comments" and "Notes", then print a report or export the items to CSV for a buyer or appraiser to read.
• Mark items with "Include in A&D Report?" (A&D means acquisition and disposition, guns coming in and going out) and use the Receipt and Disposition tabs to gather seller, buyer, date and amount. The app only keeps your own records; it files nothing.
• Keep each firearm's headspace result in "Head Space" ("go", "no-go", "field" or "not checked") and log a "Headspace Check" under "Operation" on the Maintenance tab, so the result carries a "Completion Date".
• Review the "C&R?" marker to see at a glance which pieces you have recorded as Curio and Relic firearms, which you have marked "no", and which entries are "n/a" because they are not firearms.
• Log range days, matches, hunts and appraisals on the Events tab with results, dates and costs, so each firearm carries its own record of use.

Best for: Sport shooters, hunters and owners of military surplus rifles recorded as guns, antique or black powder firearms and modern sporting arms who want purchase, maintenance and sale records kept with each piece in one searchable inventory.

Why collectors choose NM Collector CP for Firearms

Acquisition and Disposition Records for Every Firearm

Each firearm can carry a full trail. The Receipt tab records who it came from, with "License Number", address, date and amount, and the Disposition tab records who received it, with "I. D." and "D.O.B." when you need them. Use "Include in A&D Report?" as a filter in a custom report to list only the firearms marked "yes". The app keeps your own records and files nothing with any agency.

Your Serial Numbers Stay on Your Own Devices

Serial numbers and purchase details are sensitive. Your collection data is kept on your own computer or phone, the app itself never connects to the internet, and no account is needed, so no company server holds your inventory. Moving your collection between devices uses a file you handle yourself. If you choose to send that file by email or a cloud service, it passes through that provider, and the app reminds you of this before every share.

Your Records Go With You to Shows and Ranges

On Android and iOS your collection lives on the phone, so you can check what you already own, look up a serial number or read your condition notes with no signal at all, and add a new acquisition on the spot. To bring desktop and phone together, export a collection transfer file from one and import it on the other. An import replaces all data on the receiving device, so export from that device first.

Fields and Lists Built for Firearms

The template speaks the language of collecting. Lists offer 187 makers, 227 models, 67 types and 136 calibers and gauges, along with "Condition" grades that carry definitions, "Metal Finish" choices such as "parkerized" and "Cerakote", and "Head Space" results. "C&R?" and "Storage Location" sit beside them. A maker, model or caliber that is missing is one typed entry away, and every label can be renamed.

One Program for Guns and Everything Around Them

Many firearm owners also keep ammunition, knives or military items. NM Collector CP comes with 30 collection templates, including Ammo, Knives and Militaria, so each kind of item gets fields that suit it. On the Related tab you can link an accessory in one collection to a firearm in another. When no template fits, copy one or build a new template from scratch with your own labels and lists.

Documentation for Insurers, Appraisers and Heirs

A well kept record answers what an insurer, appraiser or heir asks: what the item is, where it came from, what condition it is in and what it was worth. Enter values in "Appraised Value", "Current Value" and "Insured Value" with their dates, because the software does not look up prices. Desktop canned reports include Insurance Inventory reports, with and without pictures and notes.

See How Each Field Is Filled In

The Firearms collection comes with three sample items, a Garand rifle, a Colt pistol and a Mauser rifle, that show how each field is meant to be filled in. Open them, compare them with your own guns and judge whether the template fits your collection. You can delete them or reuse them as models.

How the fields work

Every text field in a template is a drop-down field. Pick a value from the list or type your own; the + button adds what you typed to the list, the x button clears the field and the e button opens the list editor. Number fields accept any number, date fields hold dates and notes fields hold longer text. The details below cover every field on the Identification and Description tabs, and any drop-down on the other tabs that is specific to this template. Every list can be browsed in the drop-downs under Browse the full lists; lists of 10 values or fewer are also written out in full below.

Identification tab

The Identification tab holds what sets one firearm apart from another, plus the yes or no marker "Include in A&D Report?" (A&D means acquisition and disposition). The item name is built from "Custom Tag", "Manufacturer", "Importer", "Model", "Serial Number", "Type" and "Caliber Or Gauge", in that order, so the order decides how each firearm reads in lists and which fields you scan first.

Custom Tag

Drop-down · no preset values

Your own label for the item, placed first in its name. Good entries are an inventory number, a shelf code or a nickname such as Grandfather's rifle. It keeps two guns apart when they share maker, model and caliber.

This drop-down starts empty. Type a value into the field and use the + button to add it to the list; it will be there the next time you need it.

Manufacturer

Drop-down · 187 preset values

The maker or arsenal that produced the firearm, as stamped on the receiver or barrel. An entry such as "Colt", "Mauser" or "Springfield Armory" places the item in the right family, and "Custom / Gunsmith Built" covers one-off builds.

187 makers in alphabetical order, from "Aero Precision" to "Zastava". Modern commercial makers sit beside historic military arsenals and foreign state factories, and the list also offers "Custom / Gunsmith Built" and "Unknown" for pieces you cannot place.

All 187 preset values: choose “Manufacturer (Identification tab, 187 values)” in the Browse the full lists drop-downs, further down this page.

Importer

Drop-down · 31 preset values

The company that brought a foreign-made firearm into the country, whose mark is often stamped on the barrel or frame. The Mauser sample records "Century Arms International". For a gun that was never imported, either leave it empty, as the Garand and Colt samples do, or choose "None (domestic)", and keep to the same habit every time.

31 importers and distributors in alphabetical order, mostly surplus and import houses such as "Interarms", "Century Arms International" and "Navy Arms", together with "None (domestic)" for guns that never crossed a border.

All 31 preset values: choose “Importer (Identification tab, 31 values)” in the Browse the full lists drop-downs, further down this page.

Model

Drop-down · 227 preset values

The model designation the maker or military used. The sample items show "M1 Garand", "M1911A1" and "Karabiner 98k"; record the designation as marked or as it is commonly cited.

227 designations in alphabetical order, starting with numbers. Military designations and service names such as "M1 Garand" and "K98k" are mixed with commercial names such as "10/22" and "Glock 17" and historic patterns such as "Brown Bess" and "Colt Single Action Army".

All 227 preset values: choose “Model (Identification tab, 227 values)” in the Browse the full lists drop-downs, further down this page.

Serial Number

Drop-down · no preset values

The number stamped on the frame or receiver, entered exactly as it appears, including any letter prefix or suffix, as in the Mauser sample. It is the main way to prove which gun is which to an insurer, an appraiser or a buyer.

This drop-down starts empty. Type a value into the field and use the + button to add it to the list; it will be there the next time you need it.

Type

Drop-down · 67 preset values

The kind of firearm by action and form, such as "Semi-Automatic Rifle", "Bolt Action Rifle" or "Semi-Automatic Pistol". It groups the collection by kind, so you can list every "Lever Action Rifle" or every "Pump Action Shotgun" together.

67 types in alphabetical order. Most describe the action and the class of gun, for example "Lever Action Rifle", "Pump Action Shotgun" and "Percussion Revolver". A few cover related items you may also own, such as "Suppressor", "Bayonet / Scabbard" and "Weapon Case".

All 67 preset values: choose “Type (Identification tab, 67 values)” in the Browse the full lists drop-downs, further down this page.

Caliber Or Gauge

Drop-down · 136 preset values

The cartridge or shotgun gauge the firearm is chambered for, as marked on the barrel or receiver, or as confirmed by a gunsmith when unmarked or doubtful. Examples are ".30-06 Springfield", ".45 ACP" and "12 Gauge". It matters when you buy ammunition or compare similar guns.

136 entries in one alphabetical run. The first 90 are inch-based calibers such as ".17 HMR", ".223 Remington" and ".45-70 Government" (including ".410 Bore"). The rest are shotgun gauges such as "12 Gauge" and metric cartridges such as "7.62x54R", sorted together. Obsolete rounds like ".577/450 Martini-Henry" are included.

All 136 preset values: choose “Caliber Or Gauge (Identification tab, 136 values)” in the Browse the full lists drop-downs, further down this page.

Include in A&D Report?

Drop-down · 2 preset values

A yes or no marker, set per item, so a custom report can list just the guns marked "yes". A&D means acquisition and disposition, and the marker fits the Receipt and Disposition tabs, which record how each gun came in and went out.

2 values, "yes" and "no". The sample items are all set to "yes", and you can change the marker on any item whenever your records change.

All 2 preset values: no • yes

Description tab

The Description tab holds everything about the individual piece: "Nationality", "Condition" and "Condition Comments", "Metal Finish", "Head Space", "C&R?", "Stock or Grip Type", "Storage Location", "Appraised By" and "Notes", along with "Date Manufactured" and the dates and values for appraisal, current worth and insurance.

Nationality

Drop-down · 216 preset values

The country whose arsenal, army or industry the firearm belongs to, such as "United States" or "Germany". Historical entries let you record a piece by the state that issued it rather than today's map.

216 entries in alphabetical order, covering present-day countries and a number of historical states. Examples include "Germany", "Prussia (historical)" and "Soviet Union (USSR; Soviet)", along with "Confederate States (CSA)" and "Unknown".

All 216 preset values: choose “Nationality (Description tab, 216 values)” in the Browse the full lists drop-downs, further down this page.

Condition

Drop-down · 23 preset values

The overall condition grade of the firearm. A modern scale runs from factory new to poor, and a separate antique scale grades a gun by how much of it is original, so compare grades within one scale rather than across both. The Garand sample is "Very Good". Put the specifics in "Condition Comments".

23 grades in all. 7 antique grades, from "Antique Factory New" to "Antique Poor", sit beside modern grades from "New" to "Poor" and special states such as "Arsenal Refinished", "Restored" and "Relic / Non-functional". 15 of the 23 carry a definition of what the grade means, and the antique grades have the longest ones.

All 23 preset values: choose “Condition (Description tab, 23 values)” in the Browse the full lists drop-downs, further down this page.

Metal Finish

Drop-down · 23 preset values

The surface finish on the metal parts, such as "parkerized" or "blued". Finish affects appearance, corrosion resistance and often the value of a collectible.

23 finishes in alphabetical order, from "anodized" to "two-tone". Traditional treatments such as "blued", "case hardened" and "browned" share the list with modern coatings such as "Cerakote" and "Duracoat". A few, including "parkerized" and "stainless", carry a short note on how the finish behaves.

All 23 preset values: choose “Metal Finish (Description tab, 23 values)” in the Browse the full lists drop-downs, further down this page.

Head Space

Drop-down · 4 preset values

The result of a headspace check, which measures the space between the closed bolt face and the part of the chamber that stops the cartridge, usually with "go", "no-go" and "field" gauges. Record the outcome you got. The Garand and Mauser samples are recorded as "go". It is most useful for surplus rifles bought without a service history.

The list holds 4 values: "go", "no-go" and "field", which name the gauge result you recorded, and "not checked" for guns you have not had measured yet.

All 4 preset values: field • go • no-go • not checked

C&R?

Drop-down · 3 preset values

Whether you record the firearm as a Curio and Relic (C&R), a category for older or historically significant firearms tied to licensing by the US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATFE). You choose the value yourself. Choose "n/a" for an item that is not a firearm at all, such as a case or a bayonet.

The list holds 3 values, each followed by a one-line explanation: "yes" for firearms that qualify, "no" for firearms that do not, and "n/a" for items that are not firearms at all.

All 3 preset values: n/a (This is not a firearm.) • no (This is a firearm that does not qualify as a C&R for ATF licensing purposes.) • yes (This is a firearm that qualifies as a C&R for ATF licensing purposes.)

Stock or Grip Type

Drop-down · 33 preset values

The material or style of the stock on a long gun or the grips on a handgun, such as "walnut", "checkered" or "laminate". Stock and grip details affect how a collector judges originality.

33 values in alphabetical order. Woods such as "walnut", "birch" and "Circassian walnut" appear beside modern materials like "polymer" and "G10", classic grip materials such as "ivory", "pearl" and "stag", and style terms such as "thumbhole", "folding" and "Monte Carlo".

All 33 preset values: choose “Stock or Grip Type (Description tab, 33 values)” in the Browse the full lists drop-downs, further down this page.

Storage Location

Drop-down · 10 preset values

Where the firearm is physically kept or held right now, such as "Safe 1" or "Display Case". A precise location saves searching, and it also shows which guns are away from home.

The list holds 10 values that combine places, for example "Safe 1", "Display Case" and "Safe Deposit Box", with situations where the gun is out of your hands: "Gunsmith", "On Loan" and "Consignment". Add locations to match your own home.

All 10 preset values: Closet • Consignment • Display Case • Gunsmith • Off-site Storage • On Loan • Range Bag • Safe 1 • Safe 2 • Safe Deposit Box

Appraised By

Drop-down · no preset values

The name of the appraiser or firm that valued the item, such as a dealer, an auction house or an independent appraiser. Recording who gave the figure, next to "Appraised Value" and "Date Appraised", tells you how much weight to give it later.

This drop-down starts empty. Type a value into the field and use the + button to add it to the list; it will be there the next time you need it.

Condition Comments

Notes

Free text for the specifics behind the "Condition" grade: wear, marks, replaced parts, bore condition and anything a buyer would want to know. The samples mention light handling marks on a stock, holster wear on a slide and a mismatched floorplate.

Notes

Notes

Free text for the history and originality of the piece: rebuild or rebarrel dates, parts that are correct or replaced, provenance, and anything that fits no other field. The Garand sample notes a 1953 rebarrel date and correct post-war rebuild parts.

Date Manufactured

Date

The date the firearm was made, as best you can establish it from serial number tables, markings or paperwork. Even an approximate date records the era. Explain any uncertainty in "Notes".

Date Appraised

Date

The day the appraisal behind "Appraised Value" was carried out. Appraisals go stale as the market moves, so the date tells you at a glance whether the figure is recent enough to rely on.

Date Current Value

Date

The day you last set or reviewed "Current Value". Update it whenever you revise that number, so you can tell which of your own estimates are recent and which are due for another look.

Date Insured

Date

The date the "Insured Value" was set or last confirmed with your insurer, which helps you notice when coverage is due for review.

Appraised Value

Number

The amount from a formal appraisal, typed as a plain number in your own currency, such as 1800. The software does not look up prices, so this is a figure you copy in from the appraiser's report.

Current Value

Number

Your own estimate of what the firearm is worth today, entered as a number in your currency, such as 1900 against an appraisal of 1800. You update it as you follow the market.

Insured Value

Number

The amount your insurance coverage lists for the item, as a plain number in your currency, for example 2000. Comparing it with "Current Value" shows where coverage may lag behind.

Drop-downs on the other tabs

These fields belong to tabs that every collection has, but this template gives them values of its own.

Receipt tab

Business

Drop-down · 6 preset values

The seller or the channel the firearm was acquired through, such as "Gun Show", "Estate" or "Private Sale". The Garand and Mauser samples type a dealer name, Acme Surplus Arms, instead.

6 values for how a gun came to you: "Auction", "CMP (Civilian Marksmanship Program)", "Estate", "Gun Show", "Online (transfer)" and "Private Sale". A dealer name that you type can be kept in the list for next time.

All 6 preset values: Auction • CMP (Civilian Marksmanship Program) • Estate • Gun Show • Online (transfer) • Private Sale

License Number

Drop-down · no preset values

The seller's US Federal Firearms License (FFL) number when the firearm came from a licensed dealer, copied from the transfer paperwork so the acquisition record is complete. The Garand and Mauser samples fill it in; the estate purchase does not.

This drop-down starts empty. Type a value into the field and use the + button to add it to the list; it will be there the next time you need it.

Disposition tab

Business

Drop-down · 6 preset values

How or through whom the firearm left your collection, such as "Gun Show", "Private Sale" or "Trade-in". With the buyer's details and the date, it completes the acquisition and disposition trail for the item.

Choose from 6 values for how a gun leaves your hands: "Auction", "Consignment", "Estate", "Gun Show", "Private Sale" and "Trade-in". A buyer's business name that you type can be kept in the list for reuse.

All 6 preset values: Auction • Consignment • Estate • Gun Show • Private Sale • Trade-in

License Number

Drop-down · no preset values

The buyer's US Federal Firearms License (FFL) number when the firearm goes to a licensed dealer, copied from the paperwork for your disposition record. Leave it empty when the buyer holds no license.

This drop-down starts empty. Type a value into the field and use the + button to add it to the list; it will be there the next time you need it.

I. D.

Drop-down · no preset values

The identification the buyer showed, recorded as its type and number, for example a state driver license. The app keeps it on your own computer or phone unless you export or print it. It lets your disposition record show who received the firearm.

This drop-down starts empty. Type a value into the field and use the + button to add it to the list; it will be there the next time you need it.

Alien Residency Document

Drop-down · no preset values

A place to record the buyer's alien residency document details when one was presented. Leave it empty when no such document was used.

This drop-down starts empty. Type a value into the field and use the + button to add it to the list; it will be there the next time you need it.

D.O.B.

Date

The buyer's date of birth, as shown on the identification presented. It completes the buyer record alongside name, address and "I. D.", and the Mauser sample includes one.

Maintenance tab

Operation

Drop-down · 18 preset values

The maintenance job performed on the firearm, such as "Detail Strip and Clean", "Bore Inspection" or "Replace Springs". One record per job builds the service history a future owner or gunsmith will want to read.

18 jobs in alphabetical order, covering routine care such as "Clean Bore", "Lubricate" and "Safe Desiccant Change", inspections such as "Function Check" and "Headspace Check", and repairs or upgrades such as "Barrel Replacement", "Refinish" and "Trigger Job".

All 18 preset values: choose “Operation (Maintenance tab, 18 values)” in the Browse the full lists drop-downs, further down this page.

Completed Units

Drop-down · 3 preset values

Whether the job is counted in "rounds", "months" or "years". The Garand sample uses "rounds", so its service is tracked by shooting rather than by the calendar.

Choose from 3 units: "months", "rounds" and "years". Rounds suit service that depends on how much a gun is shot, while months and years suit calendar routines such as a desiccant change.

All 3 preset values: months • rounds • years

Next Due Units

Drop-down · 3 preset values

The unit used to measure when the next service falls due. It is a separate choice from "Completed Units", so a job done by round count can still be scheduled in months. The Garand sample uses "rounds" for both.

The same 3 values as the completed list: "months", "rounds" and "years". Choose whichever way you prefer to schedule the next job for that firearm.

All 3 preset values: months • rounds • years

Completed Increment

Drop-down · 7 preset values

How much use or time the recorded job covers, entered as a round count when "Completed Units" is "rounds" (250 in the Garand sample) or as a span such as "6 months". Consistent figures make it easy to compare one service with the next.

It comes with 7 ready-made values: round counts such as "50", "100", "250", "500" and "1000", and 2 time spans, "6 months" and "12 months". Any other figure can be typed and kept for later.

All 7 preset values: 100 • 1000 • 12 months • 250 • 50 • 500 • 6 months

Next Due Increment

Drop-down · 6 preset values

How much use or time should pass before the job is due again, in the units chosen in "Next Due Units". The Garand sample records 500 with rounds, alongside a "Next Due Date" a year after the service.

It has 6 values, the same as the completed list minus its smallest round count: "100", "250", "500", "1000", "6 months" and "12 months". They cover typical service intervals for shooting or storage.

All 6 preset values: 100 • 1000 • 12 months • 250 • 500 • 6 months

Events tab

Event

Drop-down · 10 preset values

The kind of occasion the firearm was used for or involved in, such as "Range Day", "Match / Competition" or "Sighting In". Logging events builds a use history, useful for recalling results and for shows and loans.

The list has 10 occasions: shooting activities such as "Range Day", "Hunt", "Sighting In" and "Match / Competition", and ownership occasions such as "Appraisal", "Auction", "Gun Show" and "Museum Loan". "Photo Session" and "Class / Training" complete the list.

All 10 preset values: Appraisal • Auction • Class / Training • Gun Show • Hunt • Match / Competition • Museum Loan • Photo Session • Range Day • Sighting In

Tabs every collection shares

Besides Identification and Description, each item has these tabs. They work the same way in every collection.

• Pictures: Attach photographs to an item, with a note, the date each was taken, a sequence number and a flag saying whether the picture belongs in reports. Pictures are copied into the application’s own folder and stay on your device.
• Receipt: Who you got the item from and when: the business or person, address, date and amount, plus notes.
• Disposition: The same layout for the other end of an item’s life: to whom it was sold, traded or given, where, when and for how much.
• Related: Link an item to other items in your collections, for example a rifle and its scope or a watch and its box.
• Maintenance: Record maintenance operations with what was done, who did it, where, what it cost, when it was completed and when the next one is due. Repeat an operation each time you perform it.
• Events: A dated log of things that happen to an item: shows, appraisals, loans, repairs and outings, with a description, results, helpers, location and cost.
• Data Sheet: A large free-form area for anything that does not fit elsewhere, such as detailed measurements or component notes.
• Links: Links to web pages, documents and pictures related to an item, each with an optional description.

The three sample items

Every new installation includes three sample items in this collection so you can see how the fields are meant to be filled in.

• Springfield Armory M1 Garand rifle in .30-06 (listed as “Springfield Armory M1 Garand 4876213 Semi-Automatic Rifle .30-06 Springfield”): The fullest sample. It fills every Identification field except "Custom Tag" and "Importer", and nearly all of Description: "Very Good" condition, "parkerized" finish, a "go" headspace result, "yes" for "C&R?", "walnut" stock, kept in "Safe 1". "Notes" records the rebarrel, and all 3 value fields and all 4 date fields are filled. It also carries Receipt, Maintenance and Events entries.
• Colt M1911A1 pistol in .45 ACP (listed as “Colt M1911A1 1287654 Semi-Automatic Pistol .45 ACP”): A lighter entry for a handgun. It fills "Manufacturer", "Model", "Serial Number", "Type" and "Caliber Or Gauge", then "Good" condition, "parkerized" finish, "checkered" grips and "Safe 1", with "Condition Comments" on holster wear and a chipped grip. "Head Space" and the Description "Notes" stay empty. Its Receipt records an estate sale with a bill of sale on file.
• Mauser Karabiner 98k imported by Century Arms (listed as “Mauser Century Arms International Karabiner 98k 7153 f Bolt Action Rifle 8x57 Mauser (8mm)”): The only sample that fills "Importer", and a serial number with a trailing letter. It shows a "blued" finish, "laminate" stock, a "go" headspace result and "Safe 2", with "Condition Comments" on a mismatched floorplate and an import mark. Only "Appraised Value" and "Current Value" are filled in. Its Disposition tab records a sale at a gun show.

Tips

• Decide how you will use "Custom Tag" before you enter many guns. It leads the item name, so whatever you type there is the first thing you see for each firearm in every list.
• Extend the lists that match your collection: add "Manufacturer" or "Model" values you handle often, and add storage locations that match your real safes and shelves.
• Enter Receipt details and provenance notes while the paperwork is still in hand, and record "Serial Number" exactly as stamped, including any letter suffix.
• Photograph the serial number, proof marks and import marks and keep the pictures on the Pictures tab.

Frequently asked questions about Firearms

Does NM Collector CP produce ATF bound book acquisition and disposition reports?

The template records the details an acquisition and disposition listing draws on: manufacturer, importer, model, serial number, type and caliber or gauge on the Identification tab, and seller and buyer details on the Receipt and Disposition tabs. On the desktop, the canned reports include a Firearms A&D report, and custom reports let you choose fields and filters. This page does not claim that any report matches an official form, and the app files nothing with any agency.

Where is my firearms data stored, and does it ever leave my devices?

Collection data is stored on your own computer or phone. The app itself never connects to the internet and needs no account, so nothing is sent to a company server. Data leaves your devices only when you send it. Share Data opens the share sheet on a phone and writes a file to a folder you choose on a computer. AirDrop, Quick Share, a USB drive or a cable keep the file on your own devices, while email or a cloud service carries it through that provider.

Can I use NM Collector CP at gun shows and ranges without an internet connection?

Yes. The app never needs the internet, and the Android and iOS apps keep your collection on the phone, so you can check what you already own, look up a serial number and add a new acquisition on the spot. Records are not synced automatically. To bring a phone and a desktop together, export a collection data transfer file from one and import it on the other. Canned and custom reports are desktop features.

How does the template handle Curio and Relic (C&R) firearms?

The "C&R?" field on the Description tab offers three values: "yes", "no" and "n/a", the last for items that are not firearms, such as a bayonet or a weapon case. You choose the value yourself, because the app does not decide whether a firearm qualifies. To review those pieces together, filter on "C&R?" in a custom report on the desktop.

What firearm-specific information can I record for each item?

Identification holds "Manufacturer", "Importer", "Model", "Serial Number", "Type", "Caliber Or Gauge", "Include in A&D Report?" and your own "Custom Tag". Description adds "Nationality", "Condition", "Metal Finish", "Head Space", "C&R?", "Stock or Grip Type" and "Storage Location", plus dates and values. Other tabs record acquisition and disposition details, maintenance jobs, events such as a match or a range day, pictures and related items.

Can I track accessories and ammunition separately from the firearms?

Yes, in two ways. Accessories can sit in the Firearms collection, since the "Type" list includes "Suppressor", "Conversion Kit" and "Weapon Case". Or keep them in their own collection, such as Ammo, and use the Related tab to link each one to a firearm, whichever collection it is in. For example, you can link a lot of ammunition to the rifle it is used with.

How do I bring my existing firearms records into NM Collector CP?

Items From CSV on the Import menu loads items that were exported from NM Collector CP, so it moves records between your own installations rather than converting another program's files. If your records are in a spreadsheet or on paper, you add items one at a time. Duplicate Item copies the identification, description and receipt details a chosen number of times, which speeds up entry of similar guns.

Does NM Collector CP work on iOS and Android, and how does it differ from the desktop?

Yes. The companion apps for iOS and Android keep your data on the phone or tablet, work with no internet connection, and let you view, add and edit items. The desktop version has extras that the mobile apps lack, including canned reports, custom reports and database backup and recovery. Move data between devices with a collection data transfer file, using the same version on both.

How do I add the Firearms template to an installation I already use?

New installations start with all 30 templates, Firearms included. If you already use NM Collector CP, download the Firearms template from the Downloads page and choose Collection Template on the Import menu. The app matches it to your collection named Firearms. For this template no field labels change, and entries already in your lists stay. If any label would change, the app lists each field and asks first. Exporting your template and items beforehand gives you a copy.

What do the three sample items in the Firearms collection show?

The Springfield Armory M1 Garand rifle is the fullest sample, with identification, condition, finish, headspace, "C&R?", storage, values and dates, plus receipt, maintenance and event entries. The Colt M1911A1 pistol is a lighter entry with an estate purchase on the Receipt tab. The Mauser Karabiner 98k imported by Century Arms shows the "Importer" field and a Disposition record for a sale. You can delete them or reuse them as models for your own guns.

Getting this template

New installations of NM Collector CP start with all 30 templates. If you already use NM Collector CP, use the Download Template button at the top of this page, unzip the file into a templates folder on your computer, and add it with File > Import > Collection Template. The app matches the collection by name, creates it if you do not have it, and asks before it changes what any field is called.

NM Collector CP is free to try with all features for 30 days, with no credit card. After that you can keep using the free version, which needs no activation, or buy an activation for the full-feature version, for 1, 2 or 5 years or for life.

If you already have a Firearms collection

If you already keep a Firearms collection, importing the refreshed template is low risk. No field labels change, so there is nothing to rename. Only the preset lists change. The refreshed template adds large, cleaned-up lists of manufacturers, models and types, a combined list of calibers and gauges, and a full list of US states for the transaction tabs. The placeholder names, addresses and license numbers that the original template shipped as samples are no longer part of it. Entries already in your lists are kept, and your data is not affected. The recommendation is to import freely.

Try it with your own collection

Every feature is free for 30 days, with no credit card, on Windows, Mac, Linux, Android and iOS. Download the free trial.
