Zaffiri Precision ZPS3 Complete Ported Slide for G19 Gen 5 | Black Barrel

The Zaffiri Precision ZPS3 Complete Ported Slide for G19 Gen 5 gives compatible compact Gen 5 builds a complete upper with integrated top-port performance, RMR optic capability, and a clean all-black profile. The Black Cerakote ZPS3 slide and Black Nitride top-ported barrel create a subdued, performance-focused setup built for Glock 19 Gen 5, Glock 19X, and Glock 45-style frames.

This upper is built for shooters who want recoil-control function without adding threaded length or an external compensator. The top-ported barrel works with the ZPS3 slide openings to vent gases upward through the slide, helping reduce muzzle rise while keeping the front end compact and non-threaded.

The all-black configuration gives this complete slide a purposeful look that fits well on practical compact builds. The Black Nitride barrel keeps the ported system visually clean through the slide cuts, while the ZPS3 machining adds the aggressive windowed profile that separates this upper from a standard replacement slide.

An RMR optic cut gives the slide a ready path for compatible red dot optics. The included optic cover plate and mounting screws keep the upper finished when an optic is not installed, while blacked-out co-witness sights provide a clean backup sighting setup around a mounted dot.

This Zaffiri Precision ZPS3 complete upper is a strong choice for Gen 5 compact Glock-compatible frames where ported performance, optic readiness, compact handling, and a complete installed parts package all need to work together. It delivers the slide, top-ported barrel, installed upper parts, recoil assembly, backplate, sights, optic cover plate, and mounting hardware in one coordinated American-made assembly.
