Zaffiri
The Zaffiri Precision ZPS.1 slide for Glock 19 Gen 3 is a factory-ready, optic-cut upgrade that transforms your duty or carry gun into a modern red-dot platform without gunsmithing. Built from 17-4 stainless steel and finished in black anodize, this slide arrives machined, coated, and ready to mount—no additional modifications needed. The optic cut is pre-machined for RMR/SRO and Holosun 407C/507C footprint optics, positioned forward of the factory rear dovetail so iron sight backup remains available.
Zaffiri Precision engineered this slide with tight tolerances to tighten groups and improve reliability. The design preserves the dovetail behind the optic cut, giving you the option to install backup sights if your mission profile demands them. Since the ZPS.1 arrives as a finished assembly, there's no waiting for custom work—unbox it, mount your optic with the included screws, and run it. The slide is incompatible with ported barrels, so confirm your barrel type before ordering if you're planning a compensated build.
Installation is straightforward: drop the ZPS.1 onto your Gen 3 frame, use the provided screws and blue Loctite for optic retention, and respect the optic manufacturer's torque specs. The slide also works with Polymer 80 PF940c frames for custom builds. Zaffiri includes a black anodized cover plate to protect the cut when you're running iron sights only.
