The GLOCK 20SF in 10mm AUTO 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 G29 also provides a safe and accurate finishing shot even when hunting big game.
