19 Other Firearms Definitions You Need To Know


Short Recoil

A semi-automatic pistol in which the barrel and breechblock are locked together for only a short distance of rearward recoil travel, at which point the two are uncoupled, the barrel is stopped and the breechblock continues rearward, extracting the spent casing from the chamber. Upon returning forward, the breechblock chambers a fresh round and forces the barrel back into its forward position. Most modern recoil operated semi-automatic pistols use short recoil.

Reactive Targets

Targets that do something when you hit them, such as fall over, burst, send up smoke, or make a noise.

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.

Slug Gun

Slang for a shotgun which is set up specifically to fire a slug (a large, single projectile) rather than shot (multiple projectiles contained within a single shell).

Over Travel

If the trigger is able to continue moving to the rear after the shot has fired, the trigger is said to over-travel.

Underbolts

A sliding bar, running longitudinally through the watertable of a break-open side-by-side gun's action, with openings through which the lumps of the barrels pass when the gun is closed. Under spring tension, this bar moves forward when the opening control is released and its two locking surfaces engage complementary slots (bites) in the rear of the two barrel lumps. Originally operated by a hinged tab in front of the trigger guard. Now invariably operated by a cam from Scott's [toplever] spindle. Most modern side-by-side guns lock closed in this manner.

Malfunction

A misfeed or other failure to fire which can be cleared on the spot and without tools.

Powder

The chemical propellant which is burned to produce the hot gases which send the projectile flying downrange.

CQB

Abbreviation for Close Quarters Battle.

Sights

The device that aids the eye in aiming the barrel of a firearm in the proper direction to hit a target.They can be a mechanical, optical, or electronic device. Iron sights or sometimes as open sights, consist of specially-shaped pieces of metal placed at each end of the barrel. The sight closest to the muzzle end of the gun is called the front sight, while the one farthest from the muzzle (and nearest to the shooter) is called the rear sight.

Cut-Away

A firearm that has had numerous careful machining cuts taken in its exterior with a view to exposing and demonstrating the functioning of critical parts of its mechanism

Wound Trauma Incapacitation

The correct technical term for the ability of a projectile to incapacitate an animal or human shot with a firearm. Incorrectly called Stopping Power.

Weaver Stance

In the Weaver stance, the body is bladed partly sideways in relation to the target rather than squared towards it (think boxing or martial arts fighter stance). The elbows are flexed and pointed downward. The strong-side arm is slightly straighter than the weak-side arm. Even though the legs are not square to tharget, the hips should be square to the target. The feet should be pointed at the target. The shooter pushes out with the gun hand, while the weak hand pulls back. This produces a push-pull tension which is the chief defining characteristic of the Weaver stance.

Falling Block

A type of action used primarily for single shot rifles whereby some kind of lever actuates a breechblock, moving it downwards in a vertical recess to expose the chamber. May have visible or enclosed hammer. For any given barrel length, it allows a shorter overall rifle length compared to a bolt action because no space is taken up by the forward-and-back cycling of the bolt. Most of the better British makers produced them in limited numbers around the turn of the last century, the Farquharson being the most iconic. Perhaps the best-known falling block action today is the Ruger No.1.

Electronic Hearing Protection

Ear muff or ear plug hearing protection that have internal electronics that amplify human voices while excluding all noises louder than a given decibel rating. Electronic hearing protection is best used when shooting outdoors. When on an indoor range they have a tendency to pick up too much echo and other muffled sounds.

Federal Assault Weapons Ban

Part of the Violent Crime Control and Law Enforcement Act of 1994. It produced a 10-year federal ban on the manufacture of new semi-automatic assault weapons with certian specifications. Firearms with specific features were defined as assault rifles. Including the AR-15, certain versions of the AK-47, the TEC-9, the MAC-10 and the Uzi, several of which had become the preferred weapon of violent drug gangs. The act also bans large-capacity ammunition magazines, limiting them to 10 rounds. The law did not apply to weapons that were already in legal possession.
Because this law was not renewed by congress in 2004, the ban was lifted.

Backstop

Anything that will safely stop a bullet and prevent it from hitting anything else after the target is struck.

CCW

Abbreviation for Concealed Carry Weapon

Mortar

An artillery piece used to fire shells over short ranges at very high trajectories.
