The Gen5 MOS slide brings practical upgrades, including front and rear serrations, an optic cut, and a durable nDLC finish. The Aftermarket Optic Cut Cover is installed to protect the MOS interface until you add an optic, and an adapter plate is included for mounting when you are ready.
The sighting system is set up for fast acquisition in varied lighting. Night Sights are installed, combining an XS high-visibility orange front with a tritium rear notch. The 6.93 in sight radius supports precise alignment.
The 4.61 in steel Glock Marksman Barrel (GMB) complements the 10mm chambering, while Glock's Safe Action system, a subtly flared magwell, and the Gen5 texture with no finger grooves provide confident handling. Ergonomics are enhanced by the Modular Backstrap System, with a palm swell accessory included to tailor the grip.
Controls are flexible and duty-ready: an ambidextrous slide stop lever and a reversible magazine release suit a variety of shooters. A frame accessory rail is present for mounting a light. Origin markings include "MADE IN AUSTRIA – GLOCK, INC., SMYRNA, GA, AT" on the barrel, and two factory 15-round magazines are included.
