Zps.5 Slide Glock 19 Gen 3 9Mm Optic Ready Sniper Gray

The Zaffiri Precision ZPS.5 slide for Glock 19 Gen 3 is a purpose-built upgrade for shooters ready to run an optic on their carry or duty gun. Machined from 17-4 stainless steel and finished in sniper gray, this optic-ready slide ships complete—cut, coated, and ready to mount. It's engineered with the tight tolerances that separate a quality aftermarket slide from the rest, giving you the accuracy and durability you expect when you're upgrading past factory specs.

The optic cut is pre-milled for RMR/SRO footprint optics, as well as popular alternatives like the Holosun 407C and 507C. The factory dovetail remains intact behind the cut, preserving your iron sight backup option. The slide comes with a black anodized cover plate and the mounting screws matched to your optic—use those screws, and a dab of blue Loctite will keep everything locked in place. Just respect the optic manufacturer's torque specs and you're golden.

This is a ready-to-ship assembly with no modifications available—what you order is what ships. It'll mate with any Glock 19 Gen 3 frame, and Zaffiri also confirms compatibility with Polymer 80 PF940c builds. Fair warning: avoid ported barrels with this slide, and note that the barrel lug is not included. This is the work of a team that understands what modern pistol shooters actually need: a robust platform to build a fast, accurate, optics-ready 9mm.

Specifications

Frequently Asked Questions

What optics will this slide accept?

The ZPS.5 is cut for RMR and SRO footprint optics. It's also compatible with Holosun 407C and 507C, plus other optics that use the standard RMR mounting pattern. The cut is milled forward of the factory rear sight dovetail, so your iron sights remain behind the optic for co-witnessing or backup.

Will this fit my Glock 19?

Yes—it's designed for Glock 19 Gen 3 frames. Zaffiri also confirms it works with Polymer 80 PF940c builds if you're assembling a frame kit. However, avoid porting on your barrel; this slide is not compatible with ported barrels.

Does it come ready to shoot?

The slide ships fully finished and optics-cut—no additional machining is needed. It comes with a black anodized cover plate and the correct mounting screws for your optic. You'll need a Glock 19 Gen 3 frame, barrel, and firing pin assembly to complete the build. Note that the barrel lug is not included with the slide.

What screws should I use to mount my optic?

Use only the mounting screws Zaffiri Precision includes with the slide. These are matched to your optic footprint. Apply blue Loctite for proper retention, and do not exceed the torque specifications set by your optic manufacturer.
