Zaffiri Precision Z-Series Ported Slide 9mm Luger RMR Cut - Fits Glock 19 Gen 3 - FDE

The Zaffiri Precision Z-Series Ported slide is a precision-machined aftermarket replacement built specifically for the 9mm Luger Glock 19 Gen 3. Each slide is cut from a single billet of 17-4 stainless steel and held to tight tolerances, delivering the durability and lock-up consistency expected of a match-grade build. It is finished in Flat Dark Earth (FDE) for a distinctive factory-plus look.

The Z-Series designation stands for factory porting: precision-machined ports along the top of the slide vent propellant gases upward at firing, helping to reduce felt recoil and muzzle rise and keeping the sights tracking on target between strings. A fiber optic front sight is installed for fast, intuitive target acquisition when running iron sights or co-witnessing with an optic.

The slide is factory-cut to accept RMR-pattern red dot optics, allowing direct mounting of Trijicon RMR and other RMR-footprint red dots without aftermarket machining. Combined with the precision-machined geometry, factory porting, and optic-ready cut, the Z-Series Ported slide gives a Gen 3 Glock 19 a meaningful functional and cosmetic upgrade. As with any aftermarket slide installation, fitting should be performed by a qualified gunsmith to ensure reliable lock-up with the host frame.
