Product Summary

The powerful yet easily carried Glock 40 Gen4 is designed to give the handgun hunter the ultimate choice in semi-automatic gaming pistol—perfect for taking down game such as whitetail deer, Russian boars, and even feral hogs. It's chambered in 10mm and combines a full 6-inch barrel for an improved velocity with a magazine capacity of 15 rounds. The Gen4 rough texturing helps shooters to retain a firm grip even in high-pressure situations.

Glock engineers have developed the Glock Modular Optic System featured on this model to simplify mounting of popular optics without costly custom machining of the pistol's slide. The MOS system comes with a cover plate for use when no optic is mounted and four plates options to comply with the specifications of some of the most trusted optic manufacturers in the industry. The MOS system also provides the option of adding tall iron sights, allowing the optic and the iron sights to co-witness. Optics not included.
