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

The Zaffiri Precision ZPS.1 slide for Glock 19 Gen 3 is a precision-engineered aftermarket upgrade built from 17-4 stainless steel and pre-cut for popular optics mounting. If you're upgrading your carry gun or building a versatile defensive platform, this optic-ready slide ships ready to go—machined to tight tolerances, coated in your choice of finish, and cut to accept industry-standard RMR-footprint optics without custom gunsmithing. The dovetail for iron sights remains behind the optic cut, so you can run both red dot and backup sights if you want.

The optics cut accommodates Trijicon RMR, Holosun 407C/507C, SRO, and other common micro red dots that share the RMR footprint. The mounting position sits forward of where the factory rear sight would go, preserving the dovetail for suppressor-height irons or standard sights. The slide ships with a black anodized cover plate and the screws your optic needs—all you have to do is torque them to spec and you're done. Zaffiri includes an information card with torque specs and mounting details; blue Loctite is recommended for peace of mind on the range or in duty use.

Built from stainless steel and finished in sniper gray, the ZPS.1 balances durability with aesthetics. The barrel channel is cut for standard Glock barrels—just note that ported barrels won't work here. The slide is sized for Glock 19 Gen 3 frames, and also fits Polymer 80 PF940C lower receivers if you're going that route. This is a stripped upper, so no barrel, springs, or internals are included; you'll need those from your donor gun or purchased separately.

Frequently Asked Questions

What optics will this slide accept?

The ZPS.1 is cut for any optic that uses the RMR footprint, including Trijicon RMR and SRO, Holosun 407C and 507C, and other compatible micro red dots. The optics mounting screws are included; refer to your optic manufacturer's torque specifications and the information card shipped with the slide.

Can I use iron sights with this optic-cut slide?

Yes. The factory dovetail for the rear sight remains intact behind the optic cut, so you can run suppressor-height irons or standard sights alongside your red dot for co-witness backup.

What's included, and what do I need to source separately?

The slide ships with the optics cover plate, black anodized, and the mounting screws for your optic. It is a stripped upper—you will need a barrel, recoil spring, and firing pin assembly from a donor gun or purchased separately to complete the build.

Is this compatible with my Polymer 80 lower?

Yes, the ZPS.1 is compatible with the Polymer 80 PF940C frame as well as the Glock 19 Gen 3. It will not fit Gen 4 or Gen 5 Glock 19 frames.
