The Glock 20 is a full size semi automatic pistol chambered in 10mm Auto. The pistol operates on Glock's Safe Action system, a striker fired mechanism incorporating three passive safeties: a trigger safety, firing pin safety, and drop safety. The Gen 4 iteration introduced several refinements over prior generations, including a reversible magazine release, a rough textured frame surface for improved purchase, a dual recoil spring assembly to reduce felt recoil, and an interchangeable backstrap system with multiple inserts to adjust grip circumference. 

This example features an FDE Cerakote finish applied to the frame and metal fiber optic front and rear sights. The factory recoil spring assembly has been replaced with a Glockmiester stainless steel guide rod. Accompanied by one 15-round magazine. No original box or accessories included.
