Description
Drop-in threaded slide assembly for the Glock 19 Gen 5. Machined from a single billet of 17-4 stainless steel by Zaffiri Precision, this ZPS.2 slide arrives complete with a 9mm barrel threaded 1/2×28 and a factory-ready RMR optic cut — no fitting, no gunsmith work.
Features
- ZPS.2 profile — Zaffiri’s flagship single-billet 17-4 stainless steel construction
- Black PVD finish on slide and matching black nitride barrel
- RMR-pattern optic cut, direct-milled (no plate stack)
- Threaded 9mm barrel, 1/2×28 TPI — accepts full-size 9mm comps and suppressors
- Fits GLOCK 19 Gen 5 frames — matches the Gen 5 slide rail geometry, not backwards-compatible with Gen 3
- American-made in Largo, Florida
Compensator pairing: The 1/2×28 muzzle threading mates cleanly with 9mm G17/G19/G26-width comps such as the 3CR 9mm Micro Comp, Strike Industries Mass Driver, or Agency Arms 417 (Gen 5-fit variant). Confirm slide-width clearance before torque.
Break-in: Run 100–200 rounds of quality 115gr/124gr FMJ before evaluating groups. As with any premium 17-4 slide, verify optic screw torque (RMR spec 15 in-lb) after the first range trip.
