Glock PG2050203: The Glock 20, in 10mm Auto, provides nothing short of massive firepower to be your reliable companion on every hunt. The use of Glock hi-tech polymer considerably reduces felt recoil. The modular backstrap design lets the user adapt the grip to hand size, and the frame surface exhibits the scientifically-designed Gen 4 rough textured technology. The Generation 4 frame retains the Glock accessory rail for accessory attachment.
