The Zaffiri Precision ZPS.3 is a ready-to-ship slide built for Glock 43 and 43X platforms that puts precision engineering and custom styling in your hands without the wait. Each slide is machined in-house from a single billet of 17-4 stainless steel and Cerakoted at Zaffiri's certified facility in Largo, Florida. You're getting American-made parts with tolerances tight enough to improve accuracy and performance right out of the box.
This slide arrives pre-cut for red dot optics and ready to run. The RMSc footprint accommodates Shield RMSc, Holosun 407k and 507k, and Sig RomeoZero sights without requiring suppressor-height iron sights. The optic cut sits forward of the rear iron sight dovetail, so you keep backup iron sight functionality if you need it. All mounting screws and a black anodized optics cover plate come with the slide.
The FDE Cerakote finish provides a durable, corrosion-resistant coating that handles daily use and concealed carry conditions. This is a stripped slide, so you'll transfer your barrel, recoil spring, firing pin, and other internals from your current setup. Installation is straightforward if you've worked with Glock parts before. The slide is not ported-compatible, so it pairs with standard barrels, not compensated or ported barrels from Zaffiri's lineup.
Mounting screws are 6-32 thread pitch. Blue Loctite is recommended for secure optics installation, and you should follow your optic manufacturer's torque specifications during setup.
Yes. The ZPS.3 is designed for both Glock 43 and 43X platforms. It fits both frames without modification. If you're running a Polymer80 PF9ss frame, this slide is compatible as well.
The RMSc footprint supports Shield RMSc, Holosun 407k and 507k, and Sig RomeoZero sights. All three use the same mounting pattern with no rear lugs and slightly lowered front lugs, so compatibility is consistent across brands.
No. This slide is not ported-compatible. Zaffiri's ported barrels only work with the ZPS.P and ZPS.4 slides. Standard, flush, and threaded barrels will function fine.
Not necessarily. The optic cut is positioned forward of the factory rear sight dovetail, allowing you to keep backup iron sights at standard height. Many users run factory-height sights alongside their red dot for backup aiming.
