Gun Descriptions

Glock 20

The GLOCK 20 Gen4, in 10mm, provides nothing short of massive firepower. The use of GLOCK hi-tech polymer considerably reduces felt recoil. With muzzle energy of 550 ft/lbs and a magazine capacity of 15 rounds, this 10mm is your reliable companion on every hunt. The Gen4 edition now incorporates a wider selection of grip dimensions to make customizing your grip even more precise.

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.
