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 new scientifically designed, real-world-tested, Gen4 rough textured technology. Internally, the new 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 Gen4 9x19mm pistol also retains the Glock accessory rail for your attachments.
Glock engineers have developed the Glock Modular Optic System featured on this model to simplify mounting of popular optics without costly custom machining of the pistol's slide. The MOS system comes with a cover plate for use when no optic is mounted and four plates options to comply with the specifications of some of the most trusted optic manufacturers in the industry. The MOS system also provides the option of adding tall iron sights, allowing the optic and the iron sights to co-witness. Optics not included.
