Zps.1 Slide Glock 19 Gen 3 9Mm Optic Ready Fde

The Zaffiri Precision ZPS.1 slide for Glock 19 Gen 3 is a purpose-built, optic-ready upgrade designed for shooters who want to mount a modern red dot without compromise. Built from 17-4 stainless steel with tight tolerances, this aftermarket slide arrives pre-cut and coated—ready to drop onto your frame and accept your optic of choice. The FDE finish gives your 9mm a modern look while the precision machining delivers the accuracy gains serious shooters demand.

The optic cut is milled to accept Trijicon RMR, SRO, Holosun 407C, 507C, and other RMR-footprint optics. The cut is positioned forward of the factory rear sight location, so your dovetail remains intact if you ever need iron backup. Zaffiri includes a black anodized cover plate and the mounting screws specific to your optic configuration—a detail that saves frustration at the range. The slide is machined steel, not cast, which means you're getting the fit and finish you'd expect from a high-end build.

This is a ready-to-ship configuration: it comes optic-cut and coated with no further modifications possible. The slide fits standard Glock 19 Gen 3 frames and is also compatible with Polymer80 PF940c frames if you're building from an 80% lower. Note that the cannel liner is not included, and this slide is not designed for use with ported barrels. Mount your optic following Zaffiri's torque specifications and the optic manufacturer's guidance, use the provided screws, and apply blue Loctite for retention.
