The Zaffiri Precision ZPS.2 complete slide for Glock 19 Gen 3 is a billet stainless steel upper built for shooters who want tighter tolerances and measurably better performance than factory. This isn't just a slide swap—it's a complete upper assembly that includes the slide, barrel, sights, and all internal parts you need to drop onto a Gen 3 frame (also compatible with Gen 1 and Gen 2). Made entirely in-house and 100% American manufactured, Zaffiri's single-piece 17-4 stainless construction is engineered to improve accuracy and reliability, making it a solid choice for defensive shooters, competition runners, and anyone serious about upgrading their carry gun.

The slide ships ready to work with modern optics. It features an RMR footprint cut (compatible with Trijicon RMR, Holosun 407C/507C/508T, SRO, and similar optics) positioned forward of where the factory rear sight dovetail would sit. This placement keeps your rear sight dovetail in place for co-witness or backup—you get flexibility without compromise. The kit includes the anodized cover plate, mounting screws specific to your optic footprint, and a flush-and-crown black nitride barrel. HD fiber sights round out the package so you're functional from day one.

Assembly is straightforward: the upper parts kit includes a polymer recoil spring assembly and everything else needed to seat the complete slide onto your frame. Zaffiri includes the correct mounting screws for your optic, and they recommend blue Loctite for proper retention. Just respect the optic manufacturer's torque specs and you're good. Note: this item cannot ship to New York or Washington.
