COLT 1911 OPTICS PLATE RMSC BLK

Description

Colt’s 1911 Optics Plate for the RMSc footprint is a direct solution for shooters who want to run a miniature red dot on a 1911 without sending the slide out for milling. The plate mounts in place of the rear sight and accepts optics cut to the Shield RMSc and Holosun 507K footprint, a compact mounting standard well suited to the narrow slide profile of the 1911 platform. Because the 1911 slide is narrower than most modern striker-fired pistols, footprint choice matters more here than on wider slides — the RMSc pattern keeps the optic centered and low without overhanging the edges.

The plate is finished in black nitride, a surface treatment that bonds into the steel rather than sitting on top of it. That means the finish holds up to the repeated slide cycling and holster wear that would eventually strip a softer coating. Stainless steel construction gives the plate corrosion resistance without adding meaningful weight to the slide’s reciprocating mass. Because even a small change in slide weight affects felt recoil and cycling reliability on a 1911, keeping the plate light and dense is the right call for a component that rides back and forth with every shot.

Installation drops in without gunsmithing on compatible Colt 1911 pistols, making this a practical upgrade path for anyone who already owns a Colt and wants to add a capable miniature optic. Verify your specific slide’s rear sight dovetail and mounting configuration before ordering to confirm compatibility with your pistol.
