C&H Precision P320 R1P/DPP to RMR/Holosun Plate with 10-8 Sight The C&H Precision V4 optic plate adapts the SIG Sauer P320 X-FIVE/M17/M18 Romeo1Pro/DPP-cut configuration to Trijicon RMR/SRO and Holosun 407C/507C/508T/507Comp optics. This black anodized package includes mounting hardware and a 10-8 rear sight. The slide cut is essential to the fit. This plate is for the P320 slides that lose their rear iron sight when the optic cover is removed. The included 10-8 rear sight is therefore a meaningful part of the configuration. Verify the exact slide cut and selected optic rather than treating the plate as universal across all P320 versions. Key Features Specific P320 slide fit: For the Romeo1Pro/DPP-cut configuration. Named optic compatibility: RMR, SRO and the Holosun C-series models. 10-8 rear sight: Included with this plate package. Mounting hardware: Included with the black anodized plate.
