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

The Zaffiri Precision ZPS.5 slide for Glock 19 Gen 3 is a purpose-built optics-ready upgrade for shooters who want a modern red-dot setup without the gunsmith visit. Machined from 17-4 stainless steel and finished in OD Green, this slide arrives pre-cut and coated—ready to mount your optic and hit the range or field. It's the kind of drop-in performance upgrade that lets you build a more capable carry or duty gun on your own timeline, and it's compatible with both factory Glock 19 Gen 3 frames and Polymer 80 PF940c builds.

Zaffiri Precision engineered this slide with tight tolerances to support accuracy and reliability. The optic cut accommodates popular RMR-footprint optics—including Trijicon RMR and SRO, and Holosun 407c and 507c—positioned forward of the factory rear-sight dovetail, so you keep iron-sight backup. The black anodized cover plate protects the cut when you're running irons, and the slide ships with the mounting screws your optic will need. Note that this is a finished, ready-to-ship part; no modifications are possible once it leaves the factory.

A few practical details: the cannel liner is not pre-installed, and this slide won't work with ported barrels. The mounting screws are specific to Zaffiri's design, and Blue Loctite is recommended to lock them in place. Always adhere to your optic manufacturer's torque specs to avoid over-tightening. This is a third-party part and is not manufactured, authorized, or warranted by Glock.
