The Zaffiri Precision ZPS.2 slide for Glock 19 Gen 3 with RMR cut is a precision-machined aftermarket upper built for shooters serious about accuracy and reliability. Crafted from billet 17-4 stainless steel at Zaffiri's facility in Largo, Florida, this slide combines tight manufacturing tolerances with American-made quality to deliver the performance you'd expect from a premium handgun upgrade. Whether you're running a stock Glock 19 Gen 3 frame or building on an aftermarket platform, the ZPS.2 provides a direct path to a modern, optics-ready carry or duty pistol.

This slide arrives pre-cut and pre-coated for the Trijicon RMR and SRO footprints, as well as Holosun 407c and 507c models—the most popular closed-emitter optics on the market. The RMR cut is positioned forward of the factory rear-sight dovetail, so you retain that mounting point if needed. The slide ships with the proper stainless-steel screws and a black anodized cover plate, ready to accept your chosen red dot. Zaffiri recommends blue Loctite for secure retention and warns against exceeding the optic manufacturer's torque specs.

Available in Armor Black (as shown), along with Magpul FDE, Sniper Grey, and Magpul OD Green, the ZPS.2 gives you both tactical versatility and aesthetic options. At 9.3 ounces and 6.75 inches long, it handles like a factory upper but with the precision engineering that separates quality aftermarket parts from the rest. Keep in mind: this slide is not compatible with ported barrels—Zaffiri makes the ZPS.P and ZPS.4 models for that purpose.

Frequently Asked Questions

Will this slide fit my Glock 19?

The ZPS.2 is designed for Glock 19 Gen 3 frames and is also compatible with Gen 1 and Gen 2 models. It also works with popular aftermarket 19-compatible frames including the SCT 19, P80 PFC9, and PSA Dagger. If you're unsure about your specific frame or build, confirm the platform before ordering.

What red dots does this RMR cut support?

The slide is pre-cut for the Trijicon RMR and SRO, as well as Holosun 407c and 507c—all based on the RMR footprint. The optic mounts forward of the factory rear-sight dovetail. Mounting screws and a black anodized cover plate are included.

Can I use a ported barrel with this slide?

No. The ZPS.2 is not compatible with ported barrels. Zaffiri offers the ZPS.P and ZPS.4 slides for that application.

What does pre-cut and pre-coated mean?

The slide arrives with the RMR optic cut already machined and the Cerakote finish already applied. No changes can be made to the slide after this point. Blue Loctite is recommended for secure optic mounting, and you should not exceed the optic manufacturer's screw torque specifications.
