Zps.5 Slide Glock 19 Gen 3 9Mm Optic Ready Fde

The Zaffiri Precision ZPS.5 slide for Glock 19 Gen 3 is a precision-machined aftermarket slide built for shooters who want tighter tolerances and optics-ready capability straight out of the box. Machined from billet 17-4 stainless steel and manufactured entirely in the USA at Zaffiri's Largo, Florida facility, this slide delivers the accuracy and performance gains that come from quality American gunsmithing. If you're building or upgrading a Glock 19 Gen 3 with a modern red dot sight, this is a no-compromise option.

The ZPS.5 arrives pre-cut and pre-coated with a certified Cerakote finish in FDE (Flat Dark Earth), so it's ready to mount your optic without additional milling work. The optic cut is machined for the RMR footprint—compatible with Trijicon RMR and SRO, Holosun 407c and 507c, and other popular red dots that use that mounting standard. The dovetail for traditional iron sights remains behind the optic cut, preserving your backup sight options. The slide ships with the proper mounting screws, a black anodized cover plate, and everything you need for installation; just use Zaffiri's provided fasteners and follow the optic manufacturer's torque spec for reliability.

Beyond Gen 3 frames, this slide is also backward-compatible with Glock 19 Gen 1 and Gen 2 platforms, and it will work with popular aftermarket frames like the SCT 19, P80 PFC9, and PSA Dagger. The combination of tight machining tolerances, American manufacturing, and pre-cut optics mounting makes this a smart choice for shooters building a duty-grade or match-ready handgun who don't want to outsource the milling work.
