Zps.3 Slide Glock 19 Gen 3 9Mm Optic Ready Sniper Gray

The Zaffiri Precision ZPS.3 slide for Glock 19 Gen 3 brings serious precision engineering to your 9mm platform. Built from billet 17-4 stainless steel and machined right here in Largo, Florida, this optic-ready slide delivers the tight tolerances and clean aesthetics that matter when you're upgrading a carry gun or building a dedicated range rig. It's pre-cut for modern red dot sights and comes finished in Sniper Gray Cerakote—a professional look that hides wear and handles duty work.

What sets the ZPS.3 apart is the commitment to American manufacturing and the no-compromise approach to the cut itself. The optic mounting surface accepts Trijicon RMR, SRO, Holosun 407C, 507C, and other RMR-footprint optics, with the cut positioned forward of the factory rear sight dovetail so you keep your irons in play. It ships with the correct mounting screws and a black anodized cover plate—details that matter when you're threading fasteners into precision work. The slide is fully finished and pre-coated; no gunsmithing required, though you'll want to use thread-locking compound and respect the optic manufacturer's torque specs during install.

Compatible with Glock 19 Gen 3 frames as well as earlier Gen 1 and Gen 2 models, the ZPS.3 also fits popular aftermarket platforms like the P80, SCT 19, and PSA Dagger—a nice bonus if you're experimenting with polymer frames. Note that this slide is not ported and won't accept Zaffiri's ported barrels; if you need a compensator-ready option, you'll want the ZPS.P or ZPS.4 instead.

The slide is cut for Trijicon RMR, Trijicon SRO, Holosun 407C, Holosun 507C, and other optics that use the standard RMR footprint. The mounting position sits forward of the factory rear sight dovetail, allowing you to co-witness your irons behind the optic.

Is this slide compatible with aftermarket frames?

Yes. Beyond Glock 19 Gen 3 frames, the ZPS.3 is compatible with popular polymer frame platforms including the P80 PFC9, SCT 19, and PSA Dagger.

What's included with the slide?

The ZPS.3 ships with the correct mounting screws for your optic cut and a black anodized cover plate. No other parts are assembled. You'll need to source your own optic, barrel, internals, and lower receiver to complete the build.

Can I use this slide with ported barrels?

No. The ZPS.3 is not ported and is not compatible with Zaffiri's ported barrel line. If you need a slide designed for compensator-equipped barrels, look at the ZPS.P or ZPS.4 models.
