The Zaffiri Precision ZPS.2 Threaded is a complete assembled slide for the Glock 17 Gen 3 frame, cut for an RMR-footprint red-dot optic and shipped with a muzzle-threaded match-grade barrel for direct suppressor or muzzle-device install. The slide is machined from a single billet of 17-4 stainless steel at Zaffiri's facility in Largo, Florida. Threaded builds pair naturally with 9mm micro compensators, thread-mount suppressors, and Q-style mounts - the exposed thread section sits proud of the flush-and-crown profile.
