Zaffiri Precision IBS Slide FDE - Fits Glock 43X - RMSc Optic Cut

The Zaffiri Precision IBS Slide is a premium aftermarket replacement slide built specifically for the Glock 43X. CNC-machined from stainless steel and finished in a durable Flat Dark Earth Cerakote, this slide delivers a custom look with a low-visibility carry profile and enhanced corrosion resistance.

Zaffiri's signature Integrated Blowhole System (IBS) porting helps reduce muzzle rise and felt recoil for faster, more controlled follow-up shots. The slide is factory-cut for the popular Shield RMSc optic footprint, allowing direct mounting of micro red dots such as the Shield RMSc, Holosun 507K, and other RMSc-pattern optics without the need for adapter plates.

Designed as a slide-only component for the Glock 43X in 9mm Luger, this IBS slide is an excellent foundation for a custom build or a premium upgrade to an existing pistol.
