The Definition of Isosceles Stance
There are two basic variants of the Isosceles stance, the
Traditional Isosceles and
Modern Isosceles stance.
In both Isosceles stances, the feet parallel pointing toward the target and are roughly shoulder width apart.
Both arms are stretched almost equally forward with the gun centered forward, creating the triangular shape which gives the stance its name.

A firing pin which moves freely forward and backward in the breechblock.
A handgun or rifle shooting sport in which the competitors attempt to knock over metallic game-shaped targets at various ranges.
A firearm loaded through the breech.
A quad stack box magazine.
In a handgun that does not have a hammer, the striker is a linear driven, spring loaded cylindrical part which strikes the primer of a chambered cartridge.
The striker replaces both the hammer and firing pin found in hammer driven pistols.
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.
Some triggers can be pulled slightly backwards before the shooter can feel any tension and before
the hammer or striker begins to retract. Pre-travel is any movement of the trigger that begins before the trigger starts to engage.
A type of gas operation for a firearm that directs gas from a fired cartridge directly to the bolt carrier or slide assembly to cycle the action.
A mechanical device that protrudes from the gun when a round is in position ready to be fired, giving a visual and tactile indication that the gun is loaded.
A catch built into the receiver of a break-open gun to keep the toplever in its extreme right position when the barrels are removed.
This device makes it slightly easier to remount the barrels. As the barrels are mounted and the breech closed,
the barrels contact some kind of release pin (marked with the arrow) and the toplever automatically returns
to the center locked position. Because, however, it requires a separate act to find and to depress this tiny
tab to re-center the toplever on a broken-down gun, this feature may be irritating when trying to put a gun away in its case.
Two firearms that are manufactured identical in every way and are sequentially serial numbered and are sold as a set.
The most common type of matched pair guns are cowboy style revolvers for a couple of reasons, both guns will feel exactly the same in the hands and they make the set more collectable.
The face of the action of a break-open firearm which houses the firing pins and receives the direct recoil of the fired round.
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.
A type of mechanism for removing a spent shell casing from the chamber of a firearm and inserting a fresh cartridge into the chamber.
This type of mechanism is most commonly used in shotguns and rimfire rifles.
A type of ammunition that utilizes a projectile or projectiles that contain a compound in its base that burns during its flight to provide a visual reference of the projectile's trajectory.
Fouling of a firearm bore by metal particles from bullets adhering to the metal surface caused by heat or friction.
