The Zaffiri Zps.3 Slide for Glock 43/43X in FDE is a precision-machined optic-ready replacement slide built for shooters who want accuracy and durability without compromise. Manufactured in-house at Zaffiri Precision's Florida facility, this single-billet 17-4 stainless steel slide is pre-cut and pre-coated to exacting standards—no gunsmithing required. It's designed to drop onto your Glock 43 or 43X frame and is already configured for modern red dot optics, making it an ideal platform for defensive carry or range work where speed and sight picture matter.

The slide comes pre-cut for Shield RMSc, Holosun 407k/507k, and Sig RomeoZero optics, all sharing the same footprint with no rear lugs and slightly lowered front lugs. That compatibility across three major optic manufacturers means you have real flexibility in your sight choice. An optics cover plate and screws are included; Zaffiri recommends blue Loctite for secure retention and specifies 6-32 thread fasteners. Keep your torque within the optic maker's spec to avoid damage.

The Magpul FDE finish pairs clean aesthetics with practical concealment. This is a no-frills, purpose-built component—not a complete slide assembly—so you'll need to source your barrel, internals, and recoil spring if you're starting from scratch. Note that this slide is not ported and will not accept Zaffiri's ported barrels; if you're interested in porting, look to their ZPS.P or ZPS.4 models instead. Made 100% in the USA with tight tolerances throughout, it represents genuine quality control from a maker that knows Glock platform inside and out.
