The GLOCK 17 Gen5 MOS is an optics upgrade of one of the most popular polymer pistols in the world. The Modular Optic System (MOS) permits mounting of red dot sights with Docter, Trijicon, C-More and Leupold footprints via adapter plates (separately available) on the slide. The integrated interface for a red dot sight is part of the metal slide. Gen5-typical features of this successful modern model ensure top performance. This is a full-size pistol, with a large frame and a long sight radius. On the dust cover there is a GLOCK-typical Weaver rail for mounting additional accessories.

As in the original, there is a trigger safety, and it is accompanied by an additional manual safety. The 18-round all-in-one magazine also holds the 12-g CO₂ capsule.
