Zaffiri Precision G19 Gen 5 ZPS.3 Slide w/ RMR Cut | FDE
The Zaffiri Precision G19 Gen 5 ZPS.3 Slide offers a straightforward path to building a top-ported Gen 5 upper without locking the pistol into that configuration permanently. Its Flat Dark Earth Cerakote finish adds a durable earth-tone exterior, while billet stainless steel construction provides the dimensional consistency and strength needed for a premium aftermarket slide assembly.
The ZPS.3 pattern removes substantial material from the forward section through three side windows on each side and a wide opening across the top. When paired with a Zaffiri Precision top-ported barrel, the upper opening gives expanding gases a direct path through the slide. The same exposed layout also puts contrasting barrel finishes on display and gives the finished upper a distinctly custom profile.
Deeply machined rear serrations provide a secure gripping surface for loading, press checks, and malfunction clearing. The slide retains compatibility with standard Glock-pattern sights and Gen 5 internal components, allowing the stripped upper to be completed with the preferred sight set, parts kit, recoil assembly, and barrel.
The direct RMR-footprint optic cut positions the red dot ahead of the rear-sight dovetail, preserving a traditional iron-sight location behind the optic. It supports popular RMR-pattern models, including the Trijicon RMR and SRO and Holosun 407C and 507C. A black anodized optic cover plate and the appropriate mounting screws are included.
In addition to Zaffiri Precision’s matching top-ported barrel, the slide accepts compatible flush-and-crown and threaded Gen 5 barrels. Fitment includes the Glock® 19 Gen 5, G19X, and G45, making this FDE ZPS.3 suitable for a compensated-style ported build, suppressor-ready threaded configuration, or distinctive full-size-grip crossover upper.
