Zaffiri Precision ZPS.4 Slide (Optic Ready) – Overview

The Zaffiri Precision ZPS.4 Slide enhances your Glock build with modern geometry, crisp machining, and an RMR-ready optic cut. Because the slide uses aggressive angled serrations, you gain improved manipulation even in fast or high-stress situations. Additionally, this design reduces weight to support faster cycling and smoother follow-up shots.

Performance-Built for Optics and Control

Zaffiri Precision engineered the ZPS.4 to balance strength and speed. The RMR-pattern optic cut allows quick installation of today’s most popular micro red dots, which helps shooters acquire their target faster. Meanwhile, the enhanced serrations and chamfered edges create better control, especially when running compensated or ported setups.

Premium Construction for Custom Builds

Each ZPS.4 slide is CNC-machined from durable materials to maintain tighter tolerances than many factory slides. This construction improves consistency, so your pistol cycles more reliably during defensive use, training sessions, or competition.

Zaffiri Precision ZPS.4 vs ZPS.3 vs ZPS.2 – Quick Comparison

The ZPS.4, ZPS.3, and ZPS.2 slides each serve different build styles, so choosing the right one depends on your shooting goals. The ZPS.4 delivers the most modern design, using sharper serrations, reduced weight, and a refined optic cut that supports faster slide manipulation and smoother cycling. Additionally, its aggressive geometry gives it the newest, performance-focused feel in the Zaffiri lineup.

Meanwhile, the ZPS.3 remains a strong option for shooters wanting aggressive styling with an RMR-ready cut, yet slightly more traditional machining lines. It balances weight, serration depth, and optic-ready capability without being as angular as the ZPS.4. If you want an optic-ready upgrade with a proven design, the ZPS.3 sits comfortably in the middle.

In comparison, the ZPS.2 caters to minimalist or classic-style builds. It removes the optic cut and focuses on a clean, iron-sight-only layout. Because of its simple geometry and lighter machining cuts, the ZPS.2 appeals to shooters who prefer a straightforward OEM-style slide with improved aesthetics but no optics.

How to Choose the Right Optic-Ready Glock Slide

Selecting an optic-ready slide depends on how you plan to use your Glock. If you run a red dot for competition, concealed carry, or defensive shooting, you need a slide with a stable optic-cut platform. The ZPS.4 excels in this area because it provides a reinforced RMR cut, aggressive serrations, and weight reduction to keep the slide balanced once the optic is installed.

Additionally, consider how much grip texture you want. Shooters operating in wet or high-speed environments benefit from the deeper serrations of the ZPS.4 or ZPS.3, while those preferring smoother handling may choose simpler designs. You should also decide whether you need a stripped slide for complete customization or a complete slide for fast installation. Because the ZPS.4 is available in both formats, it fits nearly any type of build.
