Zps.1 Slide Glock 19 Gen 3 9Mm Optic Ready Od Green
The Zaffiri Precision ZPS.1 slide for Glock 19 Gen 3 is a precision-machined optics-ready upgrade for shooters ready to modernize their setup. Built from 17-4 stainless steel and finished in OD green Cerakote, this aftermarket slide combines tight engineering tolerances with a clean, modern aesthetic. It arrives optic-cut, coated, and ready to mount—no gunsmithing required. Whether you're building a duty gun, a competition rig, or a carry pistol with red-dot capability, the ZPS.1 gives you the foundation to do it right.
The slide is cut for RMR-footprint optics including the Trijicon RMR, SRO, and Holosun 407C/507C family, with the mounting position forward of the traditional rear dovetail. The dovetail itself remains intact, so you retain backup iron sight capability if you want it. Zaffiri includes a black anodized cover plate and the mounting screws matched to your optic; you'll just need to apply Blue Loctite and torque them to the optic maker's spec. Note that this is a finished, ready-to-ship slide—optic cuts and coatings cannot be modified after purchase.
The ZPS.1 fits Glock 19 Gen 3 frames and is also compatible with Polymer80 PF940C builds. The stainless steel construction resists corrosion and wear, and the OD green finish sets it apart from the sea of black slides. One important caveat: this slide is not compatible with ported barrels, and the cannel liner is not included. As with all aftermarket Glock parts, this is not a factory Glock product and comes with no factory warranty.
