Zps.3 Slide Glock 43/43X 9Mm Optic Ready Sniper Gray
The Zaffiri Zps.3 Slide for Glock 43/43X in Sniper Gray is a precision-machined replacement slide built for shooters who want to upgrade their carry gun with optics-ready capability and American-made quality. Machined from billet 17-4 stainless steel at Zaffiri's Florida facility, this slide is engineered with tight tolerances to improve accuracy and reliability—a serious step up from factory components for dedicated carry or competitive shooters looking to modernize their 9mm platform.
The Zps.3 comes pre-cut and pre-coated for Shield RMSc, Holosun 407k/507k, and Sig RomeoZero red dot optics. All three optic cuts share the same footprint with no rear lugs and slightly lowered front lugs, so you have flexibility in which modern compact optic you choose. The mounting holes use 6-32 thread, and Zaffiri includes a black anodized cover plate and screws—just apply blue Loctite per optic manufacturer specifications and you're mounted. No gunsmithing required; no channel liner needed for G43/43X platforms.
This is a no-frills, no-assembly slide: what you receive is finished and ready to drop onto a compatible Glock 43 or 43X frame. Note that the Zps.3 is not ported-compatible; if you're running a ported barrel, you'll need the ZPS.P or ZPS.4 model instead. Available in Sniper Gray Cerakote, it pairs clean, professional aesthetics with the durability and corrosion resistance that serious shooters expect.
