The Zaffiri Precision ZPS.4 slide for Glock 17 Gen 3 in FDE is a premium aftermarket slide engineered for shooters who want tight tolerances, accuracy, and the flexibility to run a modern red dot sight. Built from billet 17-4 stainless steel and finished in durable Cerakote, this optic-ready slide is manufactured 100% in the USA at Zaffiri's facility in Florida. It's compatible with Glock 17 Gen 3 frames—and will also work with earlier Gen 1 and Gen 2 models—making it a solid upgrade path for pistol builders and gunsmiths looking to enhance an existing platform.
The ZPS.4 ships pre-cut for RMR footprint optics (including Trijicon RMR, SRO, Holosun 407c, and 507c), with the cut positioned in front of where the factory rear sight dovetail sits. That means your rear sight lives behind the optic, preserving that functional co-witness option. The slide arrives with a black anodized cover plate and the correct mounting screws, though you'll need to source your own red dot and the parts to assemble it into a complete upper. This is a slide only—no barrel, springs, or internal parts included.
FDE (Flat Dark Earth) is a natural choice for field duty, training, or duty builds where that mid-tone aesthetic works with your setup. The Cerakote finish resists wear and corrosion better than anodizing alone. Because this slide is pre-cut and pre-coated, custom modifications aren't an option—what you order is what you get, so choose your finish and optic footprint with confidence before checkout.
One important detail: Zaffiri Precision ZP ported barrels are only compatible with their ZPS.P and ZPS.4 slides. If you're upgrading from a standard Glock barrel, that's fine; ported barrels have their own home. Torque your optic screws to the manufacturer's spec and use blue Loctite for secure retention. Note that this is an aftermarket product not affiliated with or endorsed by Glock, Inc.

Yes. The ZPS.4 is designed to fit Glock 17 Gen 3 frames. It is also compatible with Gen 2 and Gen 1 models. This is a slide-only component; you'll need a compatible frame and complete your build with a barrel, springs, and firing pin.
The optic cut accommodates Trijicon RMR, SRO, Holosun 407c, and 507c, as well as other optics that use the RMR footprint. The cut is positioned in front of the factory rear sight dovetail, so you can still use your rear sight behind the optic if desired. Install your red dot using the provided mounting screws and apply blue Loctite; always follow the optic manufacturer's torque specifications.
No. This is a slide only. It does not include a barrel, springs, firing pin, or other internal parts. You'll need to source those components separately or transfer them from an existing Glock upper.
Only Zaffiri Precision ZP ported barrels are compatible with the ZPS.4. Standard Glock barrels or third-party non-ZP ported barrels should not be used with this slide.
