Summary of Firearm Use, Law, and Safety

## Introduction This study material covers practical and technical knowledge about handguns, cartridges, common malfunctions and immediate action drills, firearm components, range rules, safe handling and the fundamentals of shooting. It is designed for self-learning students who want a clear, structured overview with practical examples. > Definition: A firearm is a device designed to discharge a projectile by means of an explosive charge; a handgun is a firearm that can be held and operated with one hand or two hands. ## Cartridge types: Boxer vs Berdan (common confusion clarified) Break cartridges into components first: - Bullet (projectile) - Case (holds everything together) - Gunpowder/propellant - Primer (ignition source) ### Boxer primer - Contains a single central flash hole in the case. - The primer pocket houses the anvil as part of the primer itself. - This design makes reloading (decapping and re-priming) easier for handloaders. ### Berdan primer - Contains two (or more) offset flash holes in the case. - The anvil is part of the case (internal raised portion), not the primer. - This makes reloading more difficult because removing the spent primer is harder. > Definition: A primer is the component in the cartridge base that, when struck by the firing pin, ignites the propellant. | Feature | Boxer | Berdan | |---|---:|---:| | Flash holes | 1 | 2 (or more) | | Anvil location | In primer | In case | | Ease of reloading | Easy | Difficult | Fun fact: Boxer-primed cartridges are the most common in the United States because they simplify reloading. ## Centre-fire cartridge components (visualize each part) - Bullet: the projectile that leaves the barrel. - Gun powder: the propellant inside the case. - Case: the metal container that holds primer, powder and bullet. - Primer: located at the base of the case; ignites the powder when struck. > Definition: Centre-fire cartridge means the primer is located at the center of the case head (as opposed to rimfire where the rim contains the priming compound). ## Firearm external and internal parts — common handgun examples Learn to identify parts by model; many parts are shared across makes. ### Common external parts (present on Beretta/Z88, Glock, CZ75) - Muzzle — front end where the bullet exits - Barrel — internal tube aligned with the sights - Slide — moves rearward during recoil to eject and chamber - Frame — main body to which components attach - Grip — holds the firearm - Trigger and Trigger guard - Sights: front and rear - Magazine and Magazine release - Safety catch / Slide lock / Disassembly catch - Hammer (on hammer-fired designs) ### Common internal parts - Recoil spring and guide rod — absorb and return slide motion - Feeding ramp — guides cartridges into the chamber - Chamber — portion of barrel where cartridge sits when ready to fire - Extractor — removes the case from the chamber during ejection > Definition: The extractor is a part that grips the rim or case of a fired cartridge and removes it from the chamber as the slide moves rearward. Fun fact: Many modern service pistols use polymer frames to reduce weight while maintaining strength. ## Stoppages and malfunctions — causes and drills ### Common causes of stoppages - Dirt and fouling - Damaged or broken parts (e.g., extractor) - Faulty or incorrect ammunition - Poor handling or user error ### Immediate Action Drills (IAD) — handgun-focused 1. Failure to feed: Tap, Rack, and Continue - Tap the magazine to ensure it is seated - Rack the slide to chamber a round - Continue firing if clear 2. Failure to eject / extract: First attempt — Tap, Rack, Assess - If not fixed and results in a double feed, perform the second stoppage drill 3. Failure to fire (click/no-fire): Tap, Rack, Assess - Tap the magazine, rack the slide, attempt to fire > Definition: "Tap, Rack, and Assess/Continue" is the first immediate action drill; it addresses common simple stoppages by reseating the magazine and cycl
