G17 Gen3 Spare Slide with Standard MOS Cut — Optic-Ready Spare Slide Built for Speed and Modularity

Give your Glock G17 Gen3 a serious capability upgrade without modifying your original pistol. The G17 Gen3 Spare Slide with Standard MOS Cut is an optic-ready replacement slide engineered for shooters who want fast target acquisition, confident manipulations, and rapid field adaptability. Designed to exacting Glock dimensions and tolerances, this spare slide drops into your existing frame with minimal fuss — simply add your barrel and recoil assembly to finish the build. Whether you’re preparing a competition backup, a dedicated training slide, or a go-to optic-ready spare, this slide is one of the most impactful additions you can make among aftermarket spare slides.

Built around Glock’s MOS (Modular Optic System) footprint, the slide accepts a broad range of red-dot optics via adapter plates (sold separately). The integrated MOS cut eliminates guesswork when mounting, while the included MOS cover plate protects the cut when running iron sights only. Aggressive front serrations give positive purchase for press checks, one-handed manipulations, and rapid transitions — a real advantage in timed stages and dynamic drills. The slide ships with fully assembled internals and standard Glock sights installed so you can get shooting sooner: add barrel + recoil and you’re ready to go.

Engineered from durable, precisely machined steel and finished to resist corrosion and wear, the G17 Gen3 Spare Slide with Standard MOS Cut offers the look and function of a professional build. The slide geometry is optimized for consistent lockup and smooth cycling with quality aftermarket or factory components. For shooters focused on versatility, having a dedicated optic-ready spare slide in your kit means you can switch from iron-sight to red-dot setups without altering your carry pistol — a true tactical and logistical advantage.
