The Glock 79009 spare slide for Glock 17 Gen 3 gives you a complete, ready-to-run upper assembly that's optics-ready from the factory. Whether you're building a second upper for your 17 Gen 3, setting up a dedicated red dot configuration, or keeping a backup on hand, this OEM Glock slide comes with assembled internals and front serrations—just add your barrel, recoil spring assembly, and lower receiver to get back in the fight. It's the same uncompromising engineering that goes into every Glock pistol, because spare parts matter as much as the gun itself.
Built to Glock's exacting standards, this matte black slide features the MOS (Modular Optics System) footprint, which means you can mount a wide range of modern red dots and reflex sights without gunsmithing. The included MOS cover plate protects the mounting surface until you're ready to install glass, and those front serrations give you positive grip control whether you're racking the slide hard or running it under stress. This is genuine Glock factory hardware—no compromises on metallurgy, finishing, or tolerances.
OEM Glock parts are the gold standard for reliability and fit. If you trust your life to a Glock, you should trust only genuine Glock parts in it. This spare slide keeps your pistol in the fight or lets you experiment with different configurations without gutting your primary gun.
