Zps.3 Slide Glock 17 Gen 3 9Mm Optic Ready Od Green

The Zaffiri Precision ZPS.3 slide for Glock 17 Gen 3 is a purpose-built, optic-ready upgrade for shooters who want to run a modern red dot on their carry or duty pistol. Machined from billet 17-4 stainless steel at Zaffiri's Largo, Florida facility, this slide delivers the tight tolerances and precision fit that serious Glock users demand—all while eliminating the guesswork of aftermarket compatibility. If you're looking to modernize your Gen 3 17 with a quality optics-cut slide, this is one of the best engineered solutions available.

The ZPS.3 comes pre-cut for RMR footprint optics, accommodating Trijicon RMR, Trijicon SRO, Holosun 407C, and Holosun 507C—the red dots most shooters actually use. The cut positions the optic forward of the factory rear sight dovetail, so your backup irons remain functional and ready. You get a black anodized cover plate and the correct mounting screws in the box; Zaffiri includes a recommendation to apply blue Loctite and respect the optic manufacturer's torque specs for long-term reliability.

This OD Green Cerakote finish is durable and aesthetically paired with professional tactical builds. The slide is fully finished and ready to drop onto your Gen 3 frame—no secondary machining or fitting required. Just be aware: this is not a ported slide, so it won't accept Zaffiri's ZP ported barrels. If you want to run a compensator, stick with a standard barrel and the ZPS.3 is your match.
