Glock G17 Gen 5 MOS. Handgun

Optimized for Today’s Reflex-Style Optics


As part of the company’s Gen 5 line of handguns, Glock® introduced an all-new model of its flagship G17, complete with a number of new features found on the slide. This new package is the Glock® G17 Gen 5 MOS.

Standing for Modular Optic System, the Glock® G17 Gen 5 MOS features a slide cut just forward of the rear sight dovetail that accepts a number of attachment plates. These plates are sized to fit many of today’s popular reflex-style optics. One other feature found on the slide is the inclusion of forward slide serrations in addition to the serrations found at the rear.

  • Barrel length: 4.49 inches
  • Caliber: 9mm
  • Weight: 1.57 pounds
  • Ships with three 17-round magazines

All of these new elements found on the Glock® G17 MOS are built on the company’s Gen 5 system, which provides an improved trigger pull and removes the finger grooves found on the Gen 4 model.
