Zaffiri Precision ZPS.4 Slide (Optic Ready)

Zaffiri Precision ZPS.4 Slide (Optic Ready)

The Zaffiri Precision ZPS.4 Slide combines precision manufacturing with modern styling for Glock builders who want performance and visual impact. CNC-machined from a single billet of 17-4 stainless steel, this optic-ready slide delivers tight tolerances, improved consistency, and an aggressive windowed design that sets it apart from factory slides.

Precision-Machined for Serious Glock Builders

Zaffiri Precision machines every ZPS.4 slide from certified 17-4 stainless steel billet — a significant step above cast or lower-grade slides. The tight tolerances and heat-treated construction deliver consistent cycling, improved accuracy potential, and long-term durability under regular use. This is a slide designed for builders who refuse to compromise on quality.

Direct RMR Optic Mounting

The ZPS.4 features a precision-cut RMR footprint, allowing direct mounting of popular red dot optics without adapter plates. The optic cut is positioned in front of the factory rear sight dovetail, giving you flexibility with backup iron sights. Included with every slide is a black anodized cover plate and mounting screws — so you can run iron sights or mount your optic immediately.

Key Features and Benefits

Single Billet 17-4 Stainless Steel Construction

Machined from a single billet of 17-4 stainless steel, this slide offers exceptional strength, corrosion resistance, and durability. The material is heat-treated for reliable strength and long-term performance. This isn’t a mass-produced component — it’s a precision-machined upgrade built to last.

Aggressive Windowed Design for Reduced Weight

The ZPS.4 features Zaffiri’s signature windowed pattern — lightening cuts that reduce slide mass and speed up cycling. The result is faster return to battery, enhanced cooling, and a modern, aggressive aesthetic that showcases your barrel. The weight reduction makes a noticeable difference in how the slide tracks and cycles.

Front and Rear Serrations for Positive Manipulation

Aggressive front and rear serrations provide a secure grip for press checks, slide manipulations, and malfunction clearance — even with wet or gloved hands. The serration pattern is deeper than previous Zaffiri models for confident handling under any conditions.

Compatible with Zaffiri Precision Ported Barrels

The ZPS.4 is designed to work with Zaffiri Precision ported barrels, allowing you to run a compensated setup for reduced muzzle rise. If you’re building a performance-focused pistol, this slide is the correct foundation for Zaffiri’s ported barrel options.
