Zps.2 Slide Glock 48/43X 9Mm Optic Ready Fde

The Zaffiri Precision ZPS.2 slide for Glock 48/43X in FDE is a precision-engineered aftermarket slide built for shooters who demand tight tolerances and optic-ready capability right out of the box. Machined from billet 17-4 stainless steel and manufactured in the USA, this slide combines American craftsmanship with performance engineering—it's the kind of upgrade that rewards accuracy-focused shooters and competitive pistol builders. The optic-ready cut accepts Shield RMSc, Holosun 407K/507K, and Sig RomeoZero red dots on a unified footprint, so you're not locked into one optic ecosystem.

This is a finished, pre-coated assembly with no modifications needed or possible—the FDE Cerakote finish is applied at the factory, and the optic cut is already milled to spec. That means you're buying a complete slide ready to mate with your Glock 48 or 43X frame and lower parts kit. The black anodized optics cover plate and screws are included; just add your chosen red dot and you're in business.

Important: this slide is not ported-compatible, so it won't work with Zaffiri's ZP ported barrels. Also note that no channel liner is required for the G43/43X/48 platform. Blue Loctite is recommended for sight retention, and you should respect the optic manufacturer's screw torque specs to avoid over-tightening.

Frequently Asked Questions

Will this slide work with my Glock 43X or Glock 48?

Yes. The ZPS.2 is designed to fit the Glock 48 frame and is also compatible with the Glock 43X frame. It will not function with other Glock models.

What red dots does this optic cut accept?

The ZPS.2 optic cut is pre-milled for Shield RMSc, Holosun 407K/507K, and Sig RomeoZero red dots. All three brands share the same footprint on this slide—no rear lugs and slightly lowered front lugs—so you have flexibility in optic choice.

What's included and what do I need to provide?

The slide comes with a black anodized optics cover plate and mounting screws (6-32 thread). You'll need to supply a Glock 48 or 43X frame, lower parts kit, a compatible red dot optic, and a barrel. Note that no channel liner is required for this platform.

Can I use this slide with Zaffiri's ported barrels?

No. This slide is not ported-compatible. If you want to run a Zaffiri ported barrel, you'll need the ZPS.P or ZPS.4 slide instead.
