The Zaffiri Precision ZPS.2 RMR Cut Slide for Glock 17 Gen 3 is a billet-steel upgrade built for shooters who want tighter tolerances and a modern optics platform without the factory compromise. Machined from 17-4 stainless steel at Zaffiri's facility in Largo, Florida, this slide ships pre-cut and pre-coated for the Trijicon RMR, SRO, Holosun 407c, and 507c red dots—any optic that shares the RMR footprint. If you're running a Gen 3 Glock 17, or even a Gen 1 or Gen 2 that shares the frame, this slide delivers the accuracy and fit that makes the difference between a duty gun and a precision tool.

What sets it apart is the engineering: tight machining tolerances and 100% American manufacturing translate directly to tighter lockup and more consistent shot groups. The optic cut is positioned ahead of the factory rear dovetail (which remains intact), and you get a black anodized cover plate and the correct mounting screws in the box. That attention to detail—and Zaffiri's refusal to pre-cut ported slides without full compatibility certainty—is why these slides are trusted by serious shooters.

The ZPS.2 comes in your choice of four Cerakote finishes: Armor Black, Magpul FDE, Sniper Grey, and Magpul OD Green. This particular model is finished in Black. The slide is not compatible with Zaffiri Precision ported barrels (only the ZPS.P and ZPS.4 slides are), and mounting screws should be secured with blue Loctite and torqued to the red dot manufacturer's spec—no exceptions.

Frequently Asked Questions

Will this slide fit my Glock 17?

The ZPS.2 is designed for the Glock 17 Gen 3 frame and is also compatible with Gen 2 and Gen 1 models that share the same frame profile. If you're unsure about your frame generation, consult your pistol's documentation or the Glock factory markings on the frame.

Which red dot optics does this optic cut support?

The RMR cut is compatible with Trijicon RMR, Trijicon SRO, Holosun 407c, Holosun 507c, and any other optic that uses the standard RMR footprint. The mounting position is forward of the factory rear dovetail, leaving room for iron sight co-witness if desired.

What comes in the box?

Each ZPS.2 slide includes a black anodized cover plate and the proper mounting screws for the optic cut. You'll need to supply your own red dot, barrel, and lower receiver (or complete pistol). Blue Loctite and a torque wrench set to the optic manufacturer's specification are recommended for final assembly.

Can I use this slide with a Zaffiri Precision ported barrel?

No. The ZPS.2 is not compatible with Zaffiri Precision ported barrels. Only the ZPS.P and ZPS.4 slide models support ported barrel use. This slide works with standard, non-ported barrels.
