Zps.5 Slide Glock 19 Gen 3 9Mm Optic Ready Fde Zaffiri

The Zaffiri Precision ZPS.5 slide for Glock 19 Gen 3 is a precision-machined aftermarket slide built for shooters who run optics on their carry or duty guns. Machined from 17-4 stainless steel and finished in FDE (Flat Dark Earth), this optic-ready slide ships pre-cut and coated—ready to mount your optic and go. It's engineered with tight tolerances to support accuracy and reliability, and it's compatible with both Glock 19 Gen 3 frames and Polymer80 PF940c lower receivers, giving you flexibility whether you're building a custom pistol or upgrading an existing platform.

The optic cut is machined to accept RMR footprint optics—including Trijicon RMR, SRO, Holosun 407C, 507C, and similar designs—with the mounting position forward of the factory rear sight dovetail. This configuration lets you keep the dovetail intact for iron sight backup. The slide ships with a black anodized cover plate and the mounting screws specific to your optic, so you're not hunting for the right hardware. Just follow the optic manufacturer's torque specs (and Zaffiri recommends blue Loctite for retention) and you're ready to shoot.

Keep in mind this is a finished, ready-to-ship slide—no optic cut modifications or coating changes can be made after purchase. The slide does not include a barrel lug liner and is not compatible with ported barrels. As with all aftermarket Glock parts, this product is not manufactured or warranted by Glock itself, but it's a solid choice for anyone looking to add a modern optics platform to a proven Glock 19 platform without compromise.
