If you have a Trijicon RMR already equipped to your Glock 23 via an adapter plate, you can just remove the adapter plate and install the Glock model RMRcc plate (MPN:AC32098) to install an RMRcc. If you have your slide milled for an RMR, none of these plates will allow you to use an RMRcc. If you are just looking for a way to install your RMR to your Glock 23, you would need to use the Evolution Gun Works Trijicon RMR Sight Mount (linked below). The Trijicon RMR uses a different footprint from the RMRcc.
