Holosun 509 Adapter Plate for FN FNX-45 Black

The Holosun 509 Adapter Plate is a black mounting plate that allows an optics-ready FN FNX-45 pistol to accept Holosun reflex sights. It is designed for shooters who want to add a red dot sight to this pistol without modifying the slide.

The plate is an adapter plate type, which means it sits between the pistol's optics-ready cut and the sight, with the mounting footprint matched to the Holosun 509 series. It is listed in black to match the FNX-45 finish.

The adapter is compatible with the FN FNX-45 only, as specified by the manufacturer. Confirm the compatibility of the specific FNX-45 variant before purchase.
