Zaffiri Precision G19 Gen 3 ZPS.3 Slide w/ RMR Cut | Black

The Zaffiri Precision G19 Gen 3 ZPS.3 Slide is designed for builds that may evolve beyond a single barrel configuration. Its open machining pattern supports a matching top-ported barrel while remaining fully usable with flush-and-crown or threaded options, giving the upper greater long-term versatility than a slide dedicated to one specific setup.

Machined from billet stainless steel, the ZPS.3 features three sculpted windows along each side of the forward section and a broad opening across the top of the slide. This distinctive architecture exposes more of the barrel, gives contrasting finishes room to stand out, and provides the necessary clearance for Zaffiri Precision’s top-ported G19 barrel. Deep rear serrations create a positive gripping surface for loading, press checks, and clearing manipulations.

The Black Cerakote finish provides a durable, low-profile exterior that coordinates easily with factory-style or custom components. Standard Glock-pattern sights and Gen 3 slide internals can be used to complete the assembly, while the stripped configuration leaves the barrel, recoil system, sights, and internal parts open to individual selection.

An RMR-footprint optic cut is machined directly in front of the factory-location rear-sight dovetail. This layout maintains an iron-sight position behind the optic and supports widely used red dots such as the Trijicon RMR and SRO and Holosun 407C and 507C. The slide includes the correct optic mounting screws and a black anodized cover plate specific to the cut.

Fitment extends beyond a factory Glock® 19 Gen 3 frame to several established compact-pattern platforms, including the Ruger RXM, SCT 19, P80 PFC9, and PSA Dagger. This broad compatibility makes the ZPS.3 a strong foundation for a ported range build, optics-ready replacement upper, or completely customized compact pistol.
