The G34 Gen5 MOS pairs Glock's long-slide configuration with a 5.31-inch Glock Marksman Barrel featuring polygonal rifling, an improved crown, and an nDLC finish. This setup is designed for consistent accuracy and durability.
Gen5 design elements include the removal of finger grooves, a mildly flared magwell, ambidextrous slide stop levers, and a continuous front strap without the early Gen5 relief cut. Front and rear slide serrations provide confident manipulation.
The slide is marked "34 Gen5" and "9x19" and retains the factory MOS interface with the cover plate not installed. White-dot front and adjustable rear iron sights are factory fitted. An accessory rail is integrated into the dust cover.
Construction details include a polymer frame and nDLC-coated slide and barrel. The pistol has matching serial numbers on the slide, barrel, and frame insert, and bears "MADE IN AUSTRIA • GLOCK, INC., SMYRNA, GA" on the frame with "AUSTRIA" on the slide.
Chambered in 9mm Luger with a 17+1 capacity and a striker-fired Safe Action system, this full-size model comes with three 17-round magazines and the factory optic adapter plates to support the MOS interface.
