Zps.4 Slide Glock 17 Gen 3 9Mm Optic Ready Od Green

The Zaffiri Precision ZPS.4 slide for Glock 17 Gen 3 in OD Green is a precision-machined, optic-ready replacement slide built for shooters who want tighter tolerances, improved accuracy, and the flexibility to mount a modern red dot. Machined from billet 17-4 stainless steel and 100% made in the USA at Zaffiri's Largo, Florida facility, this slide delivers the quality and durability serious Glock users demand. The OD Green Cerakote finish is durable and professional, blending tactical function with clean aesthetics.

The ZPS.4 comes pre-cut for RMR footprint optics—compatible with Trijicon RMR and SRO, Holosun 407C and 507C, and other popular RMR-pattern red dots. The optic cut is positioned in front of the factory rear sight dovetail, so you retain your iron sight backup. The slide includes a black anodized cover plate and the proper mounting screws; you'll just need to select and mount your own optic and frame. Assembly is not included—this is a slide component only.

Zaffiri's single-billet construction and tight manufacturing tolerances are built to work seamlessly with Glock 17 Gen 3 frames, and the slide is also backward compatible with Gen 1 and Gen 2 models. If you run a ported barrel, confirm it's a Zaffiri ZP Ported model to ensure full compatibility. The pre-coat finish means no custom work is needed, but remember that no modifications can be made to this slide after purchase.

This is a no-frills, precision part for the shooter who knows what they want: a reliable, well-made upgrade that tightens up your platform and opens the door to modern optics. Not a beginner's project, but the right choice if you're building or upgrading a serious duty or competition gun.
