C&H Precision Staccato Duo Low Witness Plate For Holosun 407K/507K STID-HOLOk

The C & H Precision Staccato Duo Low Witness Plate for Holosun 407K / 507K is a premium, 1x unmagnified conversion adapter engineered to mount sub-compact reflex sights flawlessly onto optics-ready Staccato 2011 and 1911 pistol platforms. CNC-machined from lightweight, structural 6061 aluminum and protected by a black MIL-SPEC Type III hard-coat anodized finish, this low-profile plate maintains a slim deck thickness of 0.095 to 0.099 inches. It effectively transforms the factory Staccato Dawson Universal Optic (DUO) slide pocket into a form-fitting interface tailored for the Holosun K-series footprint—delivering native stability for the 407K, 507K, EPS, EPS Carry, Vortex Defender-CCW, and C & H EDC lines. To withstand intense cyclic slide forces and completely prevent hardware stripping under heavy recoil, the design incorporates patented 416 stainless steel T-nuts and replaceable T-posts that provide an industry-leading six to seven threads of maximum engagement. Operating entirely without internal electronics or battery power, this American-made mounting platform can be sourced through top tactical components distributors like Freedom Gorilla, Palmetto State Armory, and Ben Stoeger Pro Shop, arriving pre-bundled with a comprehensive stainless steel hardware kit backed by a full Lifetime Warranty.
