C&H Precision P320 Legion Steel RMR Optic Mount

The C&H Precision P320 Legion Steel RMR Optic Mount is a matte black adapter for Sig P320 Legion M17/M18 pistols with the Romeo1Pro/DPP cut. It is intended for RMR-pattern optics including Trijicon RMR/SRO and compatible Holosun C-series sights. This version gives the P320 Legion line another defined route from the factory-style cut to that optic family.

The pistol needs the R1P/DPP-style cut named in the listing, not just any P320 optic-ready slide. The sight also needs to use the RMR-pattern interface represented by the listed Trijicon and Holosun models. Checking both sides is especially important on the P320 family because several slide cuts and plate arrangements exist.

Use this version when a P320 Legion M17/M18 with the correct cut is being paired with an RMR-pattern optic. If the sight uses EPS, 509T, or another footprint, choose the corresponding adapter instead. Compare more optics and rangefinders for other P320 mounting options.
