This Glock G17 Gen 5 is a semi-automatic handgun chambered in 9mm. Its lightweight design, reliability, and ease of use make it popular among law enforcement and as a personal defense weapon. The finger grooves were removed on this model for greater versatility, and the Modular Backstrap System makes customization for different hand sizes quick and easy. The non-reflective nDLC coating on the slide resists corrosion, and the flared magwell gives the user more reloading speed. Other features include a reversible magazine catch and ambidextrous slide stop lever, as well as a match-grade Marksman Barrel with polygonal rifling for increased accuracy and improved barrel crown.
