    • Ejecting occurs when the spent cartridge is pushed out of the ejection port.
    • Cocking concludes the cycle, returning the firing mechanism to the fire position.

    Cycle of Operation (Open Action)

    • The cycle begins with loading, where a loaded magazine is inserted into the magazine well.
    • The locking phase involves the breech or back end of the barrel locking into the slide.
    • The firing phase involves the ignition of the primer and the subsequent firing of the cartridge.
    • The extraction phase involves the spent cartridge being pulled from the chamber.
    • The ejecting phase involves the spent cartridge being pushed out of the ejection port.

    Ammunition Components

    • A cartridge consists of a case, primer, powder, and bullet.
    • The case, also known as the casing, holds all parts of a round of ammunition.
    • The headstamp is a marking on the case that indicates the caliber or gauge and manufacturer.
    • Powder is a propellant that produces a large volume of gas when ignited.
    • The primer is a mixture used to ignite the propellant or powder.
    • The rim is the edge on the base of a cartridge case that stops its progress into the chamber.

    Semiautomatic Pistol Components

    • The frame or receiver holds the internal parts and slide assembly.
    • The accessory rail provides space for lighting and sighting devices.
    • The back strap is the portion of the grip placed in the palm of the shooting hand.
    • The front strap is the portion of the grip where the fingers of the shooting hand rest.
    • The hammer strikes the primer or firing pin to ignite the propellant and fire the round.
    • The magazine release releases the magazine from the frame.
    • The muzzle or barrel provides a path for the fired bullet.
    • The rear sight is located on the rear of the slide and is used for accuracy.
    • The slide houses the firing pin, barrel, recoil spring, sights, and extractor.
    • The slide lock or takedown lever allows quick and simple fieldstripping.
    • The slide stop lever locks the slide in the open position.
    • The trigger activates the pistol's operation, and the trigger guard protects the trigger.

    Magazine Components

    • The follower activates the slide stop and pushes the round up to be stripped off by the forward movement of the slide.
    • The magazine floor or butt plate holds the spring and follower in the magazine.
    • The magazine insert keeps the floor/butt plate secure and prevents dirt and debris from entering the magazine.
    • The magazine tube holds the internal components in place, including the ammunition.
    • The spring pushes the follower up.

    Cycle of Operation (Open Action)

    • The cycle of operation consists of loading, feeding/chambering, locking, firing, unlocking, extraction, ejecting, and cocking.
    • Loading involves inserting a loaded magazine into the magazine well.
    • Feeding/chambering involves moving the round from the magazine to the chamber by releasing the slide.
    • Locking involves the breech or back end of the barrel locking into the slide.
    • Firing involves the ignition of the primer and firing the cartridge.
    • Unlocking involves unseating the breech end of the barrel from the slide.
    • Extraction involves pulling the spent cartridge from the chamber.
    • Ejecting involves pushing the spent cartridge out of the ejection port.
    • Cocking involves returning the firing mechanism to the fire position.

    Recoil Management

    • Control of handgun movement during firing is crucial for accurate shooting

    • A firm grip is necessary to manage recoil, but not so tight that it affects shooting accuracy

    Squib Load Malfunction

    • A squib load occurs when the primer ignites but the powder does not burn or only partially burns.
    • This malfunction can cause a bullet to fail to exit the muzzle and become lodged in the bore.
    • A squib load is a major safety hazard.

    Identifying a Squib Load

    • A squib load is characterized by a distinct, less-loud sound, often described as a "pop" instead of a "bang".
    • The recoil felt during a squib load is significantly less than that of a regular round firing.
