Armor-Piercing Ammunition

An armor-piercing shell must withstand the shock of punching through armor plating. Shells designed for this purpose have a greatly strengthened case with a specially hardened and shaped nose, and a much smaller bursting charge.

Federal Assault Weapons Ban

Part of the Violent Crime Control and Law Enforcement Act of 1994. It produced a 10-year federal ban on the manufacture of new semi-automatic assault weapons with certian specifications. Firearms with specific features were defined as assault rifles. Including the AR-15, certain versions of the AK-47, the TEC-9, the MAC-10 and the Uzi, several of which had become the preferred weapon of violent drug gangs. The act also bans large-capacity ammunition magazines, limiting them to 10 rounds. The law did not apply to weapons that were already in legal possession.
Because this law was not renewed by congress in 2004, the ban was lifted.

Safety

A device, incorporated into the design of most firearms actions that, when engaged, should prevent the discharge of the firearm. Some safeties are more positive than others.

High Brass

By convention, powerfully loaded shotgun cartridges for hunting are generally manufactured with relatively longer brass end-caps than lower powered cartridges intended for target shooting. While different-sized brass bases are of virtually no consequence to the strength of the shell in relation to the steel breech of the gun itself, they do help the shooter identify the relative power of cartridges at a glance.

Limp Wristing

A floppy, limp wrist while shooting.

Slide Catch

Sometimes also known as a slide lock, slide release or slide lever. 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.

An opening. The ejection port is the opening in the side of a semi-auto from which spent cases are ejected.
