Zaffiri Precision ZPS2 Slide

Zaffiri Precision ZPS.2 Slide (Optic Ready)

The Zaffiri Precision ZPS.2 Slide is a single-billet precision-machined upgrade for Glock builders who want a clean, functional optic-ready slide without the wait time of custom milling [citation:1][citation:4]. Part of Zaffiri’s Ready To Ship (RTS) series, this slide is pre-cut for the RMR optic footprint and pre-coated in Black or FDE Cerakote — ready to build the moment it arrives [citation:2][citation:15].

Single-Billet 17-4 Stainless Steel Construction

Every ZPS.2 slide is machined from a single billet of 17-4 stainless steel — not cast, not forged. This gives you tighter tolerances, improved consistency, and long-term durability that mass-produced slides can’t match [citation:7][citation:15]. Zaffiri machines these in their Largo, Florida facility, 100% American made [citation:7].

RMR Optic Cut — Direct Mount, No Adapter Plate

The ZPS.2 features a precision-cut RMR footprint, allowing direct mounting of the most popular red dot optics without adapter plates. Compatible optics include the Trijicon RMR and SRO, Holosun 407C and 507C, and other RMR-pattern sights [citation:1][citation:12]. The mounting position sits in front of the factory rear sight location, with the dovetail remaining behind the optic cut for backup iron sight options [citation:1].

RTS — Ready To Ship Design

The ZPS.2 is part of Zaffiri’s Ready To Ship series, meaning the slide is already cut and coated — no waiting weeks for custom work [citation:2][citation:15]. You get the benefits of an aftermarket optic-ready slide without the downtime of sending your factory slide out for milling.

Enhanced Front and Rear Serrations

Front and rear serrations provide positive slide manipulation from any position. Whether you’re doing a press check, clearing a malfunction, or racking one-handed, the serrations give you confident grip — even with wet or gloved hands.

Broad Compatibility with OEM and Aftermarket Components

The ZPS.2 is designed for consistent fitment with standard Glock internal components and is compatible with standard Glock-pattern sights [citation:1]. It pairs seamlessly with flush and crown or threaded barrels — making it versatile for both factory upgrades and custom builds [citation:1]. This slide is also compatible with popular aftermarket frames like the Polymer80 PF940v2, SCT 19, and PSA Dagger [citation:18].

Important Compatibility Note

This slide is NOT ported compatible. Zaffiri Precision ported barrels are only compatible with the ZPS.P and ZPS.4 slides [citation:1][citation:4]. If you plan to run a ported barrel, this is not the right slide for your build.

Direct Mount — No Adapter Plate Needed

• Trijicon RMR
• Trijicon SRO
• Holosun 407C / 507C

Ideal For These Applications

Custom Glock Builds

The ZPS.2 is a favorite for custom Glock builds that want a clean, functional optic-ready slide without aggressive styling. Whether you’re creating a range-focused pistol, a carry gun, or a personalized build, this slide provides the precision foundation and clean aesthetics that builders demand [citation:11].

Polymer80 and Aftermarket Frame Builds

The ZPS.2 is compatible with popular aftermarket frames including the Polymer80 PF940v2, SCT 19, and PSA Dagger [citation:18]. For builders working with these platforms, the ZPS.2 offers a factory-spec fitment with modern optic capability.

Modernizing Gen 3 Glocks

If you have a Gen 3 Glock 17 or 19 and want to add a red dot without milling your factory slide, the ZPS.2 is a direct, no-gunsmithing solution. The RMR footprint accepts the most popular optics, and the included cover plate lets you run iron sights until you’re ready to mount a red dot [citation:19].

How to Mount Your Red Dot Optic

Required Tools & Materials

• Torx T10 screwdriver
• Blue Loctite (recommended for proper sight retention) [citation:1]
• Torque wrench (do not exceed optic manufacturer’s specifications) [citation:1]
• The mounting screws provided by Zaffiri Precision — you must use these specific screws [citation:1]

Step-by-Step Installation

1. Remove the black anodized cover plate if installed.
2. Verify your optic’s footprint matches the RMR cut on the slide.
3. Apply a small drop of Blue Loctite to each screw.
4. Mount your optic directly to the slide (no adapter plate required) using the provided screws.
5. Torque to the optic manufacturer’s specifications — do not exceed them [citation:1].
6. Apply witness marks and bore-sight or live-fire zero at your intended distance.

ZPS.2-Specific Installation Notes

• Use standard Glock internal components — the ZPS.2 is designed for OEM fitment [citation:1]
• The slide does not include a channel liner — install one before assembly
• ZPS.2 is NOT ported compatible — do not pair with a ported barrel [citation:1]
• Compatible with flush and crown or threaded barrels [citation:1]

Care and Maintenance Guide

Cerakote Finish Care

Clean with a soft cloth and mild solvent. The Cerakote finish is durable and corrosion-resistant but can show holster wear over time. Avoid abrasive cleaners that can damage the coating.

Optic Screw Maintenance

Check optic screw torque every 500 rounds. Use Blue Loctite for proper sight retention and do not exceed the optic manufacturer’s torque specifications [citation:1]. Reapply Loctite if any screw is removed.

Slide Rail Lubrication

Apply quality firearm lubricant to the slide rails after each cleaning. The tight tolerances of the ZPS.2 benefit from consistent lubrication for smooth cycling.

Channel Liner Installation

The ZPS.2 ships without a channel liner installed. Install one before assembling the slide to ensure proper striker function.
