The Zaffiri Precision ZPS.3 slide for Glock 17 Gen 3 is a precision-machined, optic-ready replacement slide built for shooters who want to upgrade their pistol's accuracy and versatility. Machined from billet 17-4 stainless steel and manufactured in-house at Zaffiri's facility in Largo, Florida, this slide delivers the tight tolerances and quality control you won't find in generic aftermarket parts. Whether you're running a duty gun, building a competition pistol, or setting up a carry gun with a modern red dot, the ZPS.3 gives you a solid foundation with professional-grade craftsmanship.
This slide arrives pre-cut and pre-coated, ready to mount optics in the RMR footprint—compatible with Trijicon RMR, Trijicon SRO, Holosun 407C, Holosun 507C, and other popular RMR-pattern red dots. The optic cut is positioned forward of the factory rear sight dovetail, so you retain that backup sight option. The slide ships with the correct mounting screws and a black anodized cover plate; you'll just need to choose your optic and add it to the gun. Zaffiri recommends blue Loctite for secure retention and advises staying within the optic manufacturer's torque specs.
Available in four Cerakote finishes—Armor Black, Magpul FDE, Sniper Grey, and Magpul OD Green—you can match your aesthetic or environment. One important note: this slide is not ported, so it won't work with Zaffiri ported barrels (those require the ZPS.P or ZPS.4). This is a straightforward, no-nonsense upgrade for Glock 17 Gen 3 shooters who value American manufacturing and precision engineering.
