About the Gun

The Gen 4 series of Glock pistols were introduced in 2010. Like most new polymer framed pistols the Gen 4 series features interchangeable grip inserts. The Gen 4 series also incorporates a dual recoil spring assembly, a feature only in previous generations' compact models. Other features include a reversible magazine release, a Tenifer matte finish slide and new grip texture. Changes in the Gen 4 design are significant enough such that not all parts can be mixed and matched with previous Glock generations.

About the Cartridge

This cartridge was developed by John Browning and was adopted by the United States Ordnance Department along with the Colt-Browning automatic pistol in 1911. It has also been made the official military handgun chambering by several other governments, notably Argentina, Mexico and Norway. The 45 Automatic is the most powerful military handgun cartridge in use today. This is a heavy and powerful sub-sonic round. Although its muzzle energy can exceed 400 ft-lbs, its velocity and bullet weight creates a steep trajectory curve that limits its effective range to self-defense distances.
