The Glock 17 Gen4, in 9x19, introduces revolutionary design changes to the world's most popular pistol. The modular back strap design lets you instantly customize its grip to adapt to an individual shooter's hand size. The surface of the frame employs the scientifically designed, real-world-tested, Gen4 rough textured technology. Internally, the Glock dual recoil spring assembly substantially increases the life of the system. A reversible enlarged magazine catch, changeable in seconds, accommodates left or right-handed operators. The G17 pistol also retains the Glock accessory rail for your attachments. This double-action-only pistol features a white dot front sight and a white outline rear sight and comes with three 17-round magazines and the original factory case. Its grips, metal, and bore are all in excellent condition.
