Gun Descriptions

Glock 17

Designed for professionals, the GLOCK 17, in 9x19, is the most widely used law enforcement pistol worldwide. Because of its unsurpassed reliability, above-average magazine capacity of 17 rounds in the standard magazine, and its low weight, it is trusted by law enforcement officers around the globe. With our revolutionary "Safe Action" trigger system, the G17 9x19 pistol is safe, easy, and quick-just what you need in high-pressure situations.

Glock 21

Remarkable for its accuracy and light recoil, the GLOCK 21SF delivers the legendary stopping power of the .45 AUTO round with 10/13 round magazine capacity. Countless law enforcement units swear by the G21SF pistol, and that's why this powerful, lightweight, all climate workhorse is standard issue from the North to South Poles. The SF model reduces the circumference of the receiver at the rear, or "back strap," offering increased comfort and controlespecially for shooters with smaller hands.
