The Definition of Modern Isosceles
In the Modern Isosceles
the feet are roughly shoulder width apart, with the gun-side foot closer to the target than the off-side foot.
The knees are flexed, and the entire body leans slightly toward the target. The shoulders are closer to the target than the hips, and the hips are more forward than the knees.
The shoulders are rotated forward and the head, rather than being upright, is vultured down behind the sights.
The entire body thus has an aggressively forward appearance, and is poised to move quickly if necessary.
19 Other Firearms Definitions You Need To Know
A firearm, usually (but not always) a fully automatic rifle, that uses a ammunition on a belt rather than a magazine to store the rounds that will be loaded into the gun.
The small dished container located on the side or top of a matchlock, wheel-lock or flintlock forearm used to hold the priming powder charge.
A rib extension on a break-open gun, ending in a circular or semi-circular shape in plan (resembling the head of a doll),
mating into a similarly-shaped recess in the top of the receiver, designed to resist the tendency of
the barrels to pull away from the standing breech when firing.
Because an action's centerpoint of flexing when firing is at the base of the standing breech, not at the hingepin, a passive doll's
head extension makes an effective extra fastener, even without additional mechanical locks operated by the opening lever.
The area of a gun range where firearms are pointed when they are fired. The area of the range forward of the firing line.
More correctly a "rifled slug" or "shotgun slug." An individual cylindrical projectile designed to be discharged from a shotgun. The term is often incorrectly used to mean a Bullet.
A small lever mounted to the cocking piece of a Mauser 98 action (and its copies such as the Springfield 1903),
rotating on a longitudinal axis from left (Fire), up to the top (Safe, but allowing bolt movement), and over to
the right (Bolt and firing pin locked Safe). While commendable for locking the firing pin instead of just the trigger,
its up-and-over arc of operation requires a scope to be mounted awkwardly high.
Paul Mauser is not to be blamed; when his safety was developed, telescopic sights were in such infancy as not to be worthy of mainstream consideration.
Two shots fired very quickly with the use of the sights.
The process of assembling cartridge case, bullet or shot, wads and primer to produce a complete cartridge with the use of
hand tools in the interest of loading for firearms for which cartridges are not available, experimenting with loads
to achieve better performance, or to save money. Not to be attempted without knowledgeable instruction and careful study of the process.
The action of an external hammer pinching or poking the web of the operator's
shooting hand between the thumb and fore-finger when the gun is fired.
A trigger that breaks (to release the hammer) easy.
Latin word meaning "for war." It is actually the proper name of the semiautomatic pistol commonly known in the USA as the "Luger.
Because of that pistol and the ammunition created for it, the common 9mm cartridge used nowadays is also known as 9mm Parabellum or 9mm Luger."
Generally refers to a .32 calibre or smaller firearm.
A generally non-magnifying optical device that has an optically collimated reticle,
allowing the user to look through a partially reflecting glass element and see a parallax free cross hair or other projected aiming point
superimposed on the field of view.
Invented in 1900 but not generally used on firearms until reliably illuminated versions were invented in the late 1970s
(usually referred to by the abbreviation "reflex sight").
A process that increases the diameter of a workpiece by compressing its length.
A shotgun with two barrels, usually of the same gauge or bore.
The two types of double-barreled shotguns are over/under (abbreviated as O/U or OU),
in which the two barrels are stacked on top of each other, and side-by-side (abbreviated as SxS),
in which the two barrels sit beside each other. See photo at right for example of side-by-side double-barreled shotgun.
For double-barreled guns that use one shotgun barrel and one rifle barrel, see combination gun.
The recoil spring is the powerful spring that cushions the slide in its rearward travel and then sends the slide forward again with enough force to drive the fresh round firmly into the chamber.
The strength of the recoil spring is calibrated to run the slide without any outside assistance.
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.
