Zaffiri Precision ZPS.3 Complete Upper Assembly for Glock 19 Gen 3 – TiN Threaded Barrel

The Zaffiri Precision ZPS.3 Complete Upper Assembly replaces the factory Glock 19 Gen 3 slide and barrel with a match-grade setup built for improved accuracy and durability. This assembly includes a machined slide, TiN (Titanium Nitride) coated threaded barrel, and recoil spring assembly—everything needed for a complete upper replacement. Shooters upgrade to the ZPS.3 for tighter tolerances, enhanced corrosion resistance, and the ability to mount a suppressor or compensator on the threaded barrel.

The slide is machined from 17-4 stainless steel with front and rear cocking serrations for positive manipulation. The TiN coating on the barrel provides exceptional wear resistance and a distinctive gold finish. This is a drop-in assembly for Glock 19 Gen 3 frames—no gunsmithing required. Compatible with factory Glock 19 Gen 3 parts and aftermarket triggers, connectors, and lower components.
