I want to mount a RMR, and I'm concerned that the supplied plastic plates may not be sufficient for the 10mm. The instructions indicate to use the one metal plate that is supplied for 40 S&W, but it is only for the Leupold DPP.
Is the supplied plastic plate adequate, or should I order the C&H metal plate?
