19 Other Firearms Definitions You Need To Know


Elevation

The setting on the sights of a firearm that controls the vertical placement and the altitude above mean sea level. This is important for long range precision shooting because the air density changes with elevation and affects the path of the bullet.

Hook

A concave, semi-cylindrical surface cut into the forward lump of a barrel set of a break-open firearm which revolves about the hinge-pin when the gun is opened.

Plinking

Informal shooting at any of a variety of inanimate targets.

Bersa

A firearms manufacturer located in the city of Ramos Mejia in Argentina. The company was founded in the mid-1950s by Italian immigrants Benso Bonadimani, Ercole Montini and Savino Caselli, all of them mechanical engineers with experience working for Beretta. Bersa is most famous for their Bersa Thunder .380 pistols and the Thunder Ultra Compact Pro Pistols (available in 9mm, .40 S&W and .45 acp). The full size Thunder combat (Thunder 9) pistol is the standard sidearm of the Argentina Armed Forces, Buenos Aires Provincial Police and several other law enforcement agencies in South America.

Reticle

A matrix of dots, posts or lines, visible inside a rifle's telescopic sight, normally adjustable via exterior knobs for windage and elevation. After careful adjustment at a known range, the shooter aims the rifle by superimposing this matrix onto the target. With good estimation or range, cooperation from the wind, a clear eye and a steady hand, he may have a reasonable expectation of hitting his target.

Crosshairs

The cross-shaped object seen in the center of a firearm scope. Its more-proper name is reticle.

Pistol Whip

Stripper Clip

Simple clips made of metal or sometimes plastic that hold several rounds of ammunition in a row and is used to quickly fill a magazine.

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.
