The Zaffiri Precision ZPS.3 Complete Upper Kit is the ultimate drop-in upgrade solution for your Glock 17 Gen 3 frame. Whether you are refreshing an existing pistol or completing a new build, this all-inclusive kit delivers precision engineering, premium materials, and a standout finish. The ZPS.3 slide is machined from a billet of 17-4 stainless steel, heat treated for maximum strength and durability, and finished in a rugged Cerakote Armor Black coating. An RMR-footprint optic cut is positioned in front of the rear dovetail, allowing seamless mounting of a red dot optic, and a black anodized optics cover plate with screws is included. The Zaffiri Match Grade barrel is machined from 416R stainless steel, stress relieved and heat treated to RC40-42 hardness, and coated in a striking Titanium Nitride Gold Tone finish. Threaded at 1/2x28, the barrel is suppressor-ready and ships with a thread protector. HD Fiber Optic sights round out the package, and every internal component you need to complete the upper assembly is included in the Upper Parts Kit. American made and built to exacting tolerances, the ZPS.3 delivers extreme performance right out of the box.
