Egw Colt Gold Cup Trijicon Rmr Sight Mount

The EGW Colt Gold Cup Trijicon RMR sight mount brings modern optics to a classic platform. If you're running a Colt Gold Cup and want to add a red dot sight without permanent modifications, this dovetail mount drops into your existing rear sight slot—no gunsmithing required. It's built from 7075 aluminum with a matte black hardcoat finish, so it'll stand up to hard use and blend seamlessly with your pistol. The mount accepts Trijicon RMR and Holosun HS507C red dots, giving you flexibility in which optic you choose.

Installation is straightforward: remove your rear sight, slip the EGW mount into the dovetail, and secure it with the included hardware. If you ever want to go back to iron sights, you can—just swap the mount out and reinstall your original rear sight. That reversibility matters if you're testing the red dot setup or need to change configurations for different shooting scenarios. The mount comes with everything you need to get running: two flat head cap screws for RMR installation and a set screw, plus an allen wrench for tightening.

This is the right choice for Colt Gold Cup shooters who want a clean, solid platform for a modern optic. The mount fits securely in the dovetail, and the aluminum construction keeps weight minimal. Whether you're building a match gun, setting up for defensive carry, or just modernizing your classic 1911, this mount gives you a reliable way to mount quality glass without permanent changes to your pistol.

Frequently Asked Questions

Will this mount fit my Colt Gold Cup?

Yes. The EGW mount is designed for the Colt Gold Cup dovetail and also fits Baby Desert Eagle (Post 2006) and EAA Witness Elite Match models. It does not fit Rock Island 1911s.

Can I use this mount if I want to keep my iron sights?

The mount replaces your rear sight, so you'll need to remove it to use this. The advantage is that it's fully reversible—you can unscrew the mount and reinstall your original rear sight at any time without any permanent changes to your pistol.

What red dot sights work with this mount?

The EGW mount is designed for Trijicon RMR and Holosun HS507C red dots. The included mounting hardware is sized for these optics.

Do I need to use Loctite when installing?

The installation instructions recommend applying blue Loctite to the mounting screws before torquing them to 15 in/lbs. A tip: place a small piece of paper between the red dot sight and the mount to prevent Loctite from getting on your optic, and it'll make removal easier if you ever need to.
