The G34 Gen5 MOS pairs Glock’s long-slide 9mm format with Gen5 enhancements. It features ambidextrous slide stop levers, a grip without finger grooves, and the Modular Backstrap System to tailor fit. The polymer frame is finished in matte black and includes the Glock accessory rail on the dustcover for compatible lights.
The slide includes both front and rear cocking serrations and a solid, uncut top. It is MOS-configured with the correct mounting plate installed, and this pistol comes with a CVLIFE micro red dot already mounted. A green fiber-optic front sight is installed for a bright aiming reference.
A threaded barrel is currently installed and fitted with a thread protector, and the factory original non-threaded barrel is included. This setup adds flexibility for muzzle-end accessories, and the protector keeps threads covered when not in use.
