Zaffiri Precision ZPS.3 Complete Upper Assembly for Glock 17 Gen 5 – TiN Threaded Barrel

The Zaffiri Precision ZPS.3 Complete Upper Assembly delivers a factory-ready upgrade for Glock 17 Gen 5 pistols. This complete upper includes a precision-machined slide, barrel, and internals, allowing shooters to add a threaded barrel option or replace worn components without purchasing parts separately. The titanium nitride (TiN) coating on the threaded barrel provides corrosion resistance and reduces friction for reliable cycling.

The slide is CNC-machined from billet steel with front and rear serrations for positive manipulation. The threaded barrel accommodates suppressors and muzzle devices. Installation is straightforward for users familiar with Glock field stripping—simply remove your existing upper and install this assembly on your Gen 5 Glock 17 frame. All internal components (firing pin, extractor, springs) are included.
