Owning a firearm is a significant responsibility that carries heavy legal and safety requirements. For the serious collector, that responsibility extends to meticulous record-keeping. Whether for insurance purposes, historical documentation, or estate planning, knowing the exact provenance and condition of every piece in a collection is essential.

The Philosophy: The Curator's Standard

This template is not a simple list; it is a professional-grade curation tool. It treats firearms as both mechanical tools and historical artifacts. By documenting everything from trigger pull weights to NICS background check numbers, it provides a level of detail that protects the owner's investment and legal standing.

The Blueprint: Technical Morphometrics

The structure of this library is divided into logical tiers of data.

  • Tier 1: Identification & Legal: The Serial Number, Manufacturer, and Model are the core identifiers. The inclusion of Purch NICS and Sold NICS booleans provides a quick reference for legal compliance history.
  • Tier 2: Technical Specifications: This is where the template excels. It tracks Action types (SAO, DA/SA, etc.), Caliber, and materials for both the Frame and Slide. Precision measurements for Trigger DA/SA and Grip Circumference are invaluable for competitive shooters who need to track how specific modifications affect performance.
  • Tier 3: Visual Documentation: Standard inventory systems offer one photo. This system provides eight dedicated image fields—Left, Right, Rear, Front, Top, Bottom, Action, and Serial. This multi-angle documentation is critical for insurance claims or proving the condition of an item during a sale.

Usage Scenarios: The Appraisal

You are preparing your collection for an annual appraisal. Instead of bringing the physical items to a dealer, you provide them with a digital export of your Memento library. They see the Appraised Value history, the high-resolution Serial and Action photos, and the detailed list of Modifications. The appraisal is faster, more accurate, and more professional because the data is already structured.

Power Feature: Barcode for Quick Access

By using the Barcode field, you can tag each storage case or safe slot. A quick scan with your phone instantly brings up the full dossier of the item inside, including its Purch Price and Condition rating, without needing to handle the firearm itself.
