The C&H Precision Staccato Duo to Holosun 407K/507K optic mount plate (part no. STID-HOLOK) lets a Staccato Duo pistol accept a red dot built to the Holosun 407K/507K 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.
