"A firearm is a tool of last resort. Respect it accordingly."
Firearm Types and Components
Instructor Sele: You cannot safely operate a tool you do not understand. This module gives you the mechanical knowledge of the firearms used at SafeHaven — so that handling, loading, clearing, and maintenance become second nature.
Section 1 — Firearm Types Used at SafeHaven
SafeHaven guards are trained on and may be issued the following: semi-automatic pistol (most common sidearm) — fires one round per trigger pull, self-ejects spent casings, fed by a detachable magazine. Common calibres: 9mm, .40 S&W.
Revolver: fires one round per trigger pull, spent casings remain in the cylinder until manually removed. Simpler mechanically, fewer malfunctions, but slower to reload.
Pump-action shotgun: used for facility defence. Each pump manually cycles the action. Effective at short range. Not a precision weapon.
Section 2 — Key Components: Semi-Automatic Pistol
Frame — the body of the pistol, houses the action. Slide — the upper moving part; cycles rearward when fired to eject the spent casing and chamber the next round. Barrel — the tube through which the bullet travels; has rifling (spiral grooves) that spin the bullet for accuracy.
Trigger — the lever that initiates the firing sequence. Trigger guard — the protective loop around the trigger; your finger must stay outside this until firing. Magazine — the detachable box that holds cartridges; inserts into the grip. Magazine release — the button that ejects the magazine. Safety — a mechanical device that blocks the firing mechanism (not all pistols have an external safety). Slide release / slide lock — locks the slide open when the magazine is empty.
Section 3 — Key Components: Revolver
Frame — the body. Cylinder — the rotating drum that holds cartridges (typically 5 or 6). Cylinder release — allows the cylinder to swing open for loading/unloading. Ejector rod — manually ejects spent casings from the cylinder. Hammer — strikes the firing pin to ignite the cartridge.
Section 4 — Ammunition Basics
A cartridge consists of four parts: case (the brass casing), primer (ignited by the firing pin), powder (propellant charge), and bullet (the projectile). Never mix calibres. Always use only the ammunition specified for your weapon — using the wrong calibre can cause catastrophic failure.
- •Know the type, calibre, and components of your issued weapon before carrying it on duty
- •Semi-automatic pistols use a detachable magazine; revolvers use a cylinder
- •Revolvers do not auto-eject — spent casings must be manually removed
- •Ammunition calibre must match the weapon exactly — no exceptions
- •Understanding your weapon's components is the foundation of safe operation
"I once watched a new guard try to chamber a round by pulling the trigger guard instead of the slide. He had been issued the weapon without proper orientation. That was a management failure, but it was also a training failure. Know your weapon. Name every part. Understand what it does. Only then should you carry it."
Revolvers differ from semi-automatic pistols in that:
