About the Gun

One of the first successful polymer framed designs, Glock handguns are common sidearms among law enforcement agencies and military organizations around the world. Although a striker-fired pistol, the Glock employs a single-action (SA) trigger, meaning that the trigger does not cock the gun, but only releases the striker when pulled. Cocking of the striker is performed by the retracting slide. Glock pistols have no manual safeties. The trigger is the only operating element. All three internal pistol safeties are deactivated when the unique single-action trigger is pulled, and automatically activated when it is released. For more information on the Glock design, please refer to the Glock pistol animation in the Basics section.

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.

Good for self defense. Too big for conceal carry

This gun performs. I really like this pistol. I like every Glock I’ve fired, but do not currently own one. This length is great for the 45ACP and tames recoil.
