Glock 40 Gen4 MOS 10mm Auto – 6.02" Long Slide, Austrian Made, 3 Magazines

The Glock 40 Gen4 MOS is a highly desirable long-slide 10mm Auto model built for shooters who want maximum sight radius, strong outdoor capability, and factory optics-ready versatility. It features a 6.02" barrel, MOS slide configuration, black polymer frame, Gen4 grip texture, and adjustable sights. GLOCK lists the G40 Gen4 MOS as a 10mm Auto model with Safe Action system, standard 15-round magazine capacity, and a long slide/barrel setup designed for improved velocity.

This Austrian-made example appears to be in excellent condition with clean exterior finish, sharp markings, and very light handling wear visible in the photos. The MOS configuration gives the buyer a ready platform for compatible reflex optics, while the Gen4 modular backstrap system and reversible magazine catch add user-fit flexibility.

Included are the factory Glock case, three magazines, and visible backstrap accessories. This is an excellent fit for 10mm fans, outdoor use, range work, hunting/trail carry, or anyone looking for one of Glock’s most capable long-slide 10mm platforms.
