19 Other Firearms Definitions You Need To Know


POA

Abbreviation for Point of Aim

Improved Cartridge

A wildcat cartridge that is created by straightening out the sides of an existing case and making a sharper shoulder to maximize powder space. Frequently the neck length and shoulder position are altered as well. The caliber is NOT changed in the process.

Muzzle Control

Being aware of and responsible of which direction your firearm is pointed at all times, and always keeping it pointed in a safe direction.

Jaws

The vise-like device on a flintlock hammer used to hold the flint.

Collateral Damage

Damage that is unintended or incidental to the intended outcome.

Burst Mode

A firing mode enabling the shooter to fire a predetermined number of rounds with a single pull of the trigger.

Timing

The proper adjustment of the various interrelated moving parts of a gun so that every operation works in proper sequence, such as that the two ejectors of a double gun kick out the spent cases at the same instant and with the same force.

Makarov

The Soviet Union's standard military and police side arm from 1951 to 1991 replacing the Tokarev TT-33 semi-automatic pistol and the Nagant M1895 revolver. Designed by Nikolay Fyodorovich Makarov, it is a blowback operated semiautomatic pistol which fires the 9x18mm Makarov cartridge, and holds 8 rounds in the magazine.

Head

Head [of a Stock]. The forward end of a buttstock, where it meets the receiver and accepts the bulk of the gun's recoil when fired.

Snap Shot

A quick shot taken without deliberate aim.

Hinge Pin

A short cylindrical rod of hardened steel running laterally near the front of the bar of a break-open gun's action around which the barrel hook revolves when the gun is opened. Over the decades, this pin and its complimentary hook can wear and a gun can sometimes "shoot loose" or "come off the face." The proper cure for this condition is to replace the hinge pin with a new one, slightly oversized, to compensate for wear on both itself and on the barrel hook.

Ear Plugs

Hearing protection that fits inside the ear canal.

Obturation

The process of a bullet expanding under pressure to fit the bore of the firearm, or a cartridge case expanding under pressure to seal the chamber.

Grip Safety

A passive, external safety typically located on the backstrap, which must be fully depressed to release the trigger. Most 1911-pattern pistols feature a grip safety.

Penetration

The distance travelled by a projectile from the point where it strikes the target to the point where it stops.

Firearm

A firearm is a portable gun (pistol or rifle), being a barreled weapon that launches one or more projectiles often driven by the action of an explosive force.

Turk's Head

A tip for a cleaning rod, a jag, with spirally-radial wires for vigorously scrubbing a gun's bore.

Magazine Follower

Same as Follower. A plate, mounted to the top of a spring, inside a magazine, over which cartridges may slide smoothly as they are guided into the chamber of a repeating firearm.

Choke

A constriction at or near the muzzle of a shotgun barrel that affects shot dispersion.
