Letter K Firearms Glossary
Usually referred to as a Kentucky Long Rifle or simply Longrifle, the Kentucky Rifle is a flintlock rifle with a long barrel and short, crooked stock. It is widely believed to be a largely unique development of American rifles that was uncommon in European rifles of the same period.
The Kentucky Long Rifleis an early example of a firearm using rifling, (spiral grooves in the bore). This gave the projectile, commonly a round lead ball, a spiraling motion, increasing the stability of the trajectory.
Rifled firearms saw their first major combat usage in the American colonies during the Seven Years war, and later the American Revolution in the eighteenth century.
A horizontal wedge, press-fit through the forend of a vintage gun, through a lump
attached to the underside of the barrel and out the other side of the forend.
To secure the forend in position. Also called a crosspin or a wedge fastener.
The tendency of a bullet to tip in flight and hit a target sideways, leaving a distinctly oblong hole.
This destabilization of the spinning bullet in flight is typically caused by a bullet weight inappropriate
for the rate of twist of the rifled barrel, an out-of-balance bullet or its having nicked an impediment such as a blade of grass, in flight.
The curved, forward end of the bar of a break-open firearm's action, about which the mounted
forend iron revolves downward. This area should be kept lightly greased to avoid galling the bearing surfaces.
A metal surface which contains a pattern of ridges or beads.
German for "short." Seen as part of a cartridge designation. On some German manufactured guns that use .380 ACP, the designated caliber is 9mm Kurtz (9mm Short), which is also the same as the Italian 9mm Corto
13 Other Firearms Definitions You Need To Know
The frame designation that Smith and Wesson uses for their extra large framed revolvers like the S&W Model 500 and S&W 460XVR
An extra-deep magazine typical of large calibre rifles for dangerous game. The line of the underside of the wrist does not carry straight forward as with ordinary rifles.
Rather the rear of the magazine aligns more towards the center of the forward edge of the triggerguard,
typically allowing at least one extra cartridge to be carried.
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.
Also known as collimating sight or occluded eye gunsight, a Collimator Sight is
a type of optical "blind" sight that allows the user looking into it to see an illuminated aiming point aligned
with the device the sight is attached to regardless of eye position (parallax free).
The user can not see through the sight so it is used with both eyes open while one looks into the sight,
with one eye open and moving the head to alternately see the sight and then at the target, or using one
eye to partially see the sight and target at the same time.
Targets that do something when you hit them, such as fall over, burst, send up smoke, or make a noise.
A lever on a break-open gun mounted to the top of the receiver which, when pushed with the thumb (normally) to the right, operates (usually) a
Scott Spindle, which in turn withdraws (usually) a Purdey Underbolt from the bites in the lumps of the barrels,
allowing them to hinge downwards and the gun to open.
A firearm whose barrels are hinged, and rotate perpendicular to the bore axis to expose the breech and allow loading and unloading of ammunition.
A stock on a long gun that can be shoved into itself to shorten it, either for storage or to make the gun fit shooters of different sizes.
A common type of iron sights in which the rear sight is an open-topped U or a V or a square-notch shape and with a
blade type front sight, in contrast to the closed circle commonly found in aperture sights.

The term is misused by the media to mean more than one firearm or any quantity of ammunition, as in "they found an arsenal."
A hinged plate covering the bottom of a rifle magazine and extending rearward on either side of the triggerguard.
This design allows it to be more securely fastened for one more imperceptible step towards total reliability.
The act of setting up a telescopic or other sighting system so that the point of impact of a bullet matches the sights at a specified distance.
