Zps.5 Slide Glock 19 Gen 3 9Mm Optic Ready Black
The Zaffiri Precision ZPS.5 slide for Glock 19 Gen 3 is a purpose-built upgrade for shooters who want a clean, modern platform ready for optics. Built from 17-4 stainless steel and finished in durable black anodizing, this optic-ready slide arrives pre-cut and coated—no gunsmithing required. It's designed to fit standard Glock 19 Gen 3 frames and is also compatible with Polymer 80 PF940c builds, making it a versatile choice whether you're upgrading a factory gun or finishing a serialized frame.
The optic cut is machined for RMR-footprint red dots, including Trijicon RMR and SRO, Holosun 407C and 507C, and similar competitors. The cut is positioned forward of the original rear sight dovetail, so you retain the factory sight channel behind the optic mounting area. The slide ships with a black anodized cover plate and mounting screws sized for your chosen optic—critical details that prevent the guesswork and wrong hardware from undermining your build. Zaffiri includes the right fasteners; just follow the optic manufacturer's torque spec (blue Loctite recommended) and you're ready to shoot.
This is a finished, ready-to-ship unit with no customization options—the machining, anodizing, and optic cut are locked in. Note that the slide does not include a channel liner and is not compatible with ported barrels. If you're building or upgrading a Glock 19 Gen 3 and want a solid aftermarket slide with clean tolerances and optics mounting already dialed in, the ZPS.5 cuts out the middle steps.
