Zaffiri Precision ZPS3 FDE Complete Ported Slide for G43X | Black Barrel

The Zaffiri Precision ZPS3 FDE Complete Ported Slide for G43X gives compatible Glock 43 and Glock 43X slimline builds a complete optic-ready upper with FDE Cerakote styling, a Black Nitride top-ported barrel, and installed upper components. This configuration adds integrated ported performance to the slimline platform while keeping the overall build compact, non-threaded, and clean at the muzzle.

The top-ported barrel is the main advantage of this ZPS3 assembly. Instead of adding length with a threaded barrel and external compensator, the ported barrel vents through the matching slide openings to help control muzzle rise. For a G43X-style build, that creates a flatter-tracking upper while preserving the shorter front-end profile that makes the slimline platform so useful.

The FDE Cerakote slide and Black Nitride barrel pairing gives this version a practical two-tone appearance. The black barrel stays visually restrained through the ZPS3 windows, while the FDE slide adds enough contrast to separate the build from a standard all-black upper. It is a strong fit for a compact pistol that needs performance-focused porting without an overly flashy finish combination.

The ZPS3 slide profile is cut around the ported-barrel layout, with open window styling and a large topstrap port that gives the barrel proper clearance. The result is a coordinated slide-and-barrel system rather than a standard slide paired with an unrelated barrel upgrade. That matters on a ported setup, where alignment, clearance, and slide geometry all need to work together.

The RMSc optic cut supports popular slimline red dot optics, including Shield RMSc, Holosun 407K / 507K, Sig RomeoZero, Holosun EPS Carry, and similar-height compatible optics. Zaffiri Precision includes the optic cover plate and mounting screws, while the blank blacked-out co-witness sights provide a clean backup sighting setup with or without an optic installed.
