Zps.2 Slide Glock 19 Gen 3 9Mm Optic Ready Od Green

The Zaffiri Precision ZPS.2 slide for Glock 19 Gen 3 is a precision-machined, optic-ready replacement slide built for shooters who want better accuracy and reliability than factory. Machined from a single piece of 17-4 stainless steel and finished in Magpul OD Green Cerakote, this slide combines rugged durability with clean aesthetics. It's manufactured in Largo, Florida, and comes pre-cut and pre-coated for RMR-footprint red dot optics—no gunsmithing required. Whether you're building a carry gun, a duty pistol, or upgrading an existing Gen 3 frame, this is a serious alternative to factory Glock slides.

The ZPS.2 is designed and tested to fit Glock 19 Gen 3 frames, and is also compatible with Gen 1 and Gen 2 models. It will also work with aftermarket frames including the SCT 19, P80 PFC9, and PSA Dagger. The optic cut accommodates Trijicon RMR, SRO, and Holosun 407C/507C optics, with the mounting position forward of the factory rear sight dovetail—so you keep the dovetail slot for co-witnessing irons if you want them. A black anodized cover plate and mounting screws are included.

One critical note: this slide is not ported and is not compatible with Zaffiri's ported barrels (those fit the ZPS.P and ZPS.4 only). The slide arrives as-is—pre-cut, finished, and ready to install on a compatible frame. Zaffiri recommends blue Loctite on the optic screws and strict adherence to your optic manufacturer's torque spec to prevent movement or damage.
