Product Summary

The Glock 34 Gen4, in 9x19, introduces revolutionary design changes to the tactical/practical Glock designed to be the same overall length as the Government Model 1911 pistols. The modular backstrap design lets you instantly customize its grip to adapt to an individual shooter's hand size. The surface of the frame employs Glock's scientifically-designed, real-world-tested, Gen4 rough textured technology. Internally, the Glock dual recoil spring assembly substantially increases the life of the system. A reversible enlarged magazine catch, changeable in seconds, accommodates left or right-handed operators.

This model comes quipped with the M.O.S. (Modular Optic System), with plates for mounting optics from EOTech, Docter, Insight, Meopta, Trijicon RMR, C-MORE, and Leupold Delta Point to the slide without costly custom machining. A cover for use when optics aren't in place is included as well. Optic sold separately.
