C&H Precision FN509509TST Optic Adapter Plate - FN 509/510/F 545 - Holosun 509T Footprint - Black Steel

The C&H Precision FN509509TST is a precision-machined steel optic adapter plate engineered to mount a Holosun 509T red dot directly to the slide of FN 509, FN 510, and FN 545 pistols. Cut specifically for the 509T footprint, this plate drops into the factory optic-ready cut on these FN slides and provides a secure, repeatable mounting interface between the optic and the pistol.
