The GLOCK G17 Gen4 9x19 Pistol features a Modular Back Strap design that lets you customize the grip to fit your hand size without altering the grip angle and the Safe Action® system, which consists of 3 independent, automatic safeties that help prevent unintentional firing. The pistol is made with a cold hammer-forged barrel with a Nitration finishing process and has a reinforced polymer frame with Gen4 rough-textured technology. Accessory rail. This one is like new and appears to be possibly unfired, but I cannot confirm that as it may have been just cleaned really well. Comes as is with one magazine and no box.
