Zps.3 Slide Glock 17 Gen 3 9Mm Optic Ready Fde

The Zaffiri Precision ZPS.3 slide for Glock 17 Gen 3 9mm is a purpose-built optic-ready upgrade that brings precision engineering to one of the most popular defensive and range platforms. Machined from billet 17-4 stainless steel and manufactured entirely in the USA at Zaffiri's Florida facility, this slide combines tight tolerances with clean, modern aesthetics — and it arrives pre-cut and pre-coated, ready to install. If you're building a modern carry gun, upgrading a duty pistol, or setting up a competition shooter, a quality aftermarket slide like this one unlocks better accuracy and lets you mount the red dot sight of your choice without compromise.

The ZPS.3 is cut for RMR and SRO footprint optics as well as Holosun 407c and 507c models — some of the most trusted red dots on the market. The optic cut is positioned ahead of the factory rear sight dovetail, preserving that backup iron sight capability. The slide ships with the correct mounting screws, a black anodized cover plate, and guidance on proper installation (Loctite is recommended, and respecting the optic maker's torque spec is essential). Choose your color: Armor Black, Magpul FDE, Sniper Grey, or Magpul OD Green — the FDE version shown here offers a classic, versatile look that works for duty or field use. One important note: this slide is not compatible with ported barrels; if you're running a ZP ported barrel, you'll want the ZPS.P or ZPS.4 model instead.

Built to exacting standards and backed by a reputation for quality, a Zaffiri slide transforms the feel, function, and potential of your Glock Gen 3 platform — whether you're ringing steel at distance, training for concealed carry, or chasing accuracy on the clock.
