Zps.6 Slide Glock 17 Gen 3 9Mm Optic Ready Od Green

The Zaffiri Precision ZPS.6 slide for Glock 17 Gen 3 is a purpose-built, optic-ready upper that turns your carry or duty gun into a modern pistol without a full build. Machined from 17-4 stainless steel and finished in OD green, this is a drop-in replacement slide designed to tight tolerances for reliable function and improved accuracy. It arrives cut and coated—ready to mount your optic and shoot—so there's no gunsmithing or guesswork required.

The optic cut accommodates RMR footprint optics, including the popular Trijicon RMR and SRO, as well as Holosun 407C and 507C models. The mounting position sits forward of the factory rear sight dovetail, which remains intact and usable as a backup. Zaffiri includes a black anodized cover plate and the correct mounting screws for your optic; just apply Blue Loctite per their spec and stay within the optic manufacturer's torque limits. Note that this slide is not compatible with ported barrels and does not include a barrel, firing pin, or other internal components—you'll need a complete parts kit or your existing G17 Gen 3 internals to finish the build.

Whether you're upgrading a duty pistol, building a dedicated range gun, or going the Polymer 80 route (this slide also fits the PF940v2 frame), the ZPS.6 delivers the fit and finish of a quality aftermarket component at a realistic price. The OD green anodize is a clean, modern look that resists wear and corrosion better than bare steel.
