Zaffiri Precision Z Series Ported Slide – Glock 19 Gen 3, Black

The Zaffiri Precision Z Series ported slide (brand part no. SL-G19G3-ZP-RMR-BLK) is machined from a single billet of 17-4 stainless steel for the Glock 19 Gen 3, finished in an Armor Black Cerakote with forward and rear serrations. Zaffiri Precision built the Ported Z line to cut both weight and felt recoil, using two rows of three ports on each side of the top to bleed gas and reduce muzzle rise. The slide ships optic-ready with a Trijicon RMR footprint that also accepts Holosun 407C and 507C-pattern optics, complete with mounting screws and a black anodized cover plate for when no optic is installed. Competitive and duty-minded Glock 19 shooters use this slide to add a red dot and cut recoil in the same upgrade.
