C&H Precision HK VP9 Optic Plate for Holosun 407K/507K

The C & H Precision HK VP9 Plate for Holosun 407K / 507K is a premium, 1x unmagnified optics conversion adapter designed to mount sub-compact reflex sights flawlessly onto factory optics-ready Heckler & Koch pistol slides. CNC-machined to ultra-tight tolerances from structural 6061-T6 aluminum and protected by a black MIL-SPEC Type III hard-coat anodized finish, this low-profile plate maintains a slim baseline thickness of 0.095 to 0.099 inches. It seamlessly transforms the factory HK slide pocket into a form-fitting, sub-compact interface tailored for the Holosun K-series footprint—delivering native stability for the 407K, 507K, EPS, EPS Carry, Olight Osight S, and C & H EDC lines. To counter aggressive 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.
