Zaffiri Precision ZPS.3 Compensated Ported Slide for Glock 17 Gen 3 – Black

The Zaffiri Precision ZPS.3 Compensated Ported Slide is a direct replacement upper for Glock 17 Gen 3 pistols, designed to reduce muzzle rise and improve follow-up shot speed. The integrated vertical ports direct gas upward during firing, countering barrel lift without adding external compensators or barrel extensions. This slide is machined from 17-4 stainless steel and features front and rear serrations for positive manipulation under stress.

The black finish is applied using a Physical Vapor Deposition (PVD) process for superior wear resistance and corrosion protection. This is a drop-in component compatible with factory Glock 17 Gen 3 frames, barrels, and internal parts. No permanent modifications or gunsmithing required—simply transfer your existing barrel, recoil spring assembly, firing pin assembly, and extractor.
