Glock Complete MOS Slide for Glock 19 Gen 3, Black

The Glock Complete MOS Slide for Glock 19 Gen 3 (brand part number 79008) is a genuine factory replacement slide finished in black matte, built for shooters who want a drop-in upgrade or a spare slide for their Glock 19. Because it’s a Modular Optic System (MOS) slide, it’s cut and ready to accept a red dot optic, and it ships complete rather than as a bare slide casting. Glock assembles the internals at the factory and includes both the MOS cover plate and the pistol’s standard sights, so the slide is ready to install and run without sourcing extra small parts. It’s the same slide Glock puts on factory MOS-configured Glock 19 Gen 3 pistols, and it carries no aftermarket compatibility guesswork since Glock builds it in-house.
