The Definition of Slide Catch
Sometimes also known as a
slide release or
On a semi-autmatic gun, the lever or catch that holds the slide open (after the last round is fired or when racking an empty gun).
Typically they are located on the left side of the frame about mide barrel. Some of the newer semi-automatic pistols have an
internal slide lock. Even though on pistols with an external slide catch, you can push down on the lever to release the slide,
it should never be used in such a manner. The proper way to release the slide is to rack the slide.

Any type of accessory that can be attached to a firearm's rail.
A plain, functional, unembellished firearm used to hunt in rough terrain where one might prefer not to put a more expensive, deluxe grade gun at risk of damage.
Refers to a visible dark ring created by the primers in centerfire ammunition around the firing pin hole in the frame after much use.
The distance that equates the exit pupil size of a rifle scope's
ocular lens to the entrance pupil of the user, in order to achieve the largest, unvignetted view.
This distance must be sufficient to ensure that the ocular rim of the scope does not lacerate the shooter's
eyebrow upon recoil. And, the scope should be positioned so that eye relief is suitable when the rifle is comfortably mounted.
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.
A moon clip is a ring-shaped or star-shaped piece of metal designed to hold multiple cartridges together as a unit, for simultaneous insertion and extraction from a revolver cylinder.
Unlike a speedloader, a moon clip remains in place during firing, and after firing, is used to extract the empty cartridge cases.
Helical grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis.
This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy.
A line, either imaginary or marked, from which people shoot their firearms down range.
The relationship between a bullet's weight and its diameter. A long bullet, such as the original 7.62x54R
loading for the Mosin Nagant 91/30, will have a high sectional density and consequently greater
penetration than a shorter bullet of similar construction. A shorter bullet with less sectional
density will have relatively less penetration, but greater knockdown power.

The thumb-piece on the top rear of the hammer that enables it to be manually drawn back to full cock.
A type of expanding bullet with a concavity in its nose to increase expansion on penetration of a solid target.
Some hollow-point's are also designed to fragment as they expand. They are least likely to
over-penetrate the target and harm an innocent bystander. Commonly used for self-defense.
Also known as a Flash Hider. A muzzle attachment intended to reduce visible muzzle flash caused by the burning propellant.
Flash reducers lessen glare as seen by the shooter, but do not hide the flash from other observers to the front or side of the firearm.
A firearm is loaded when a cartridge is in its firing chamber. However, for safety reasons all firearms are always treated as loaded at all times.
The entire process of making the trigger complete its journey past the trigger break.

A type of small arms ammunition that eliminates the cartridge case that typically holds the primer, propellant, and projectile together as a unit.
