The Definition of 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.

A type of gun barrel rifling where the traditional lands and grooves are replaced by "hills and valleys" in a rounded polygonal pattern, usually a hexagon or octagon.
Polygons with a larger number of edges provide a better gas seal in relatively large diameter polygonally rifled bores.
A firearm's ability to be fired fully automatically, semi-automatically or, in some cases, in burst-fire mode at the option of the firer.
The wearing of the portion of the barrel where the gas pressure and heat is highest as the projectile leaves the chamber.
The greater the chamber pressure the more rapid throat erosion occurs which is compounded by rapid firing which heats and weakens the steel.
An underpowered powder charge, usually caused by a fault in cartridge loading, often insufficient to expel a projectile from the muzzle of a firearm.
If such a blockage is not cleared, the next attempted shot could cause the barrel at least to bulge, and very possibly to burst.
The entire collection of moving parts which work together to fire the gun when the trigger is pulled.
It may include trigger springs, return springs, the trigger itself, the sear, disconnectors, and other parts.
Plugs of hardened steel, precisely machined in relation to the standard dimensional specifications of a given cartridge,
normally in sets of three: "GO", "No-Go" and "Field". By loading these plug-gauges into the chamber in succession,
one can check that the action should close on the "Go" gauge. It should not close on the "No-Go" gauge,
but might were enough force to be used. And, it absolutely should not close on the "Field" gauge.
Any type of accessory that can be attached to a firearm's rail.
The official US military designation for the Colt .45 semiautomatic pistol adopted by the US in 1911.
The gun was designed by John Moses Browning, and produced by Colt.
During trials, the Browning-Colt design beat out several competing designs, including one from Savage and a .45 caliber version of the German Parabellum ("Luger").
The M1911 saw its first combat in the Philippines and then in World War I.
Early use showed that it could be improved and in 1921 the M1911A1 was introduced, which featured a few changes like a reocontoured frame,
shorter trigger, and a rounded backstrap. The M1911A1 remained the standard US military handgun until it was replaced in the 1980's by the Beretta M9.
However, it remains very popular with civilian shooters in the US, and has been modified extensively to update it to
conform to more modern theories of handgun usage.
Pulling the slide back to its rearmost position, and then letting it go forward under its own spring tension.
Racking the slide loads the chamber and prepares the gun to fire in a semi-automatic handgun.
Not putting your finger on the trigger until your sights are on target, then pulling the trigger smoothly, and following through by realigning the sights before allowing your finger to come off the trigger.
A smooth bore long gun that shoots a group of pellets called shot instead of bullets.
Depending on the bore size and the size of the pellets there may be from less than 10 to two hundred or more pellets in a single shotgun cartridge.
Shotguns are designed for shooting moving targets (such as flying birds or running rabbits) at close range.
A semi-automatic firearm malfunction in which the slide passes entirely over the fresh round, failing to pick it up to insert into the chamber as the slide returns to battery.
Sloppy movement (slack) of a trigger before the actual point of let-off.
Short, interchangeable cylinders, of
subtly different internal tapers, that screw into a threaded recess at the muzzle of a
shotgun. By inserting different choke tubes, one can alter the shot pattern thrown by the
On a semi-automatic pistol, or any other firearm in which the trigger is at some distance from the sear, this is an intermediate piece connecting the two parts.
A type of small arms ammunition that eliminates the cartridge case that typically holds the primer, propellant, and projectile together as a unit.
The substance which imparts movement to the projectile in a firearm. In a firearm, usually powder. In an airgun the propellant is air or Co2
