The Zaffiri Precision ZPS.3 slide for Glock 43 and 43X pistols is a precision-engineered aftermarket slide built for shooters who demand accuracy and reliability. Machined from billet 17-4 stainless steel with tight tolerances, this optic-ready Glock 43/43X slide is 100% American-made at Zaffiri's facility in Largo, Florida. It arrives pre-cut and pre-coated in Magpul OD Green Cerakote, ready to mount a red dot without additional gunsmithing—a significant advantage for anyone looking to modernize their carry or range gun quickly.

The ZPS.3 is cut to accept Shield RMSc, Holosun 407K/507K, and Sig RomeoZero optics, all using the same footprint with no rear lugs and slightly lowered front lugs for consistent compatibility. An optics cover plate and mounting screws (6-32 thread) are included. The slide does not include a channel liner, which is not required for the G43, 43X, or 48 platforms. Important note: this slide is not ported-compatible; if you're running a ported barrel, you'll need Zaffiri's ZPS.P or ZPS.4 models instead.

This is an unassembled slide—it ships without internals or frame—so you'll either be installing it on an existing Glock 43 or 43X frame or pairing it with a new one. We recommend using blue Loctite on the optic mounting screws and adhering to the optic manufacturer's torque specs to ensure safe, secure installation. Whether you're building a compact duty gun, an EDC, or upgrading an existing 43/43X, a quality billet slide like this one noticeably tightens shot groups and improves the shooting experience.
