The C&H Precision FN 509 to Holosun 509T optic mount plate (part no. FN509-509T-ST) lets a FN 509 pistol accept a red dot built to the Holosun 509T mounting footprint. C&H Precision designs, machines, and ships every plate from its family-owned business in Coastal Georgia, cutting each one on HAAS CNC machines to tight tolerances so the optic sits low and square with no wobble. It is a straightforward, direct-fit upgrade for shooters running this pistol for concealed carry, duty, or competition who want a specific red dot footprint without sending the slide out for custom milling.
