The G34 Gen5 MOS combines Glock's long-slide 9x19 layout with a 5.31 inch Glock Marksman Barrel to deliver a longer sight radius and refined accuracy potential. It uses Glock's Safe Action system with a factory trigger pull of approximately 24 N.
Gen5 updates include the removal of finger grooves, ambidextrous slide stop levers, and a subtly flared magwell to support smooth reloads. The slide has front and rear serrations, a solid top, and the factory MOS interface with a cover plate installed.
Sight configuration is factory sights. A Glock accessory rail is integrated into the polymer frame.
Markings include the slide legend "34 Gen5 AUSTRIA 9x19," Austrian proof marks, and the AT barrel code. The frame is marked "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." Capacity is 17+1 with the included factory 17-round magazines. Note: The slide serial number differs from the frame serial.
