With regard to a hypothetical marriage of a Glock 48 MOS and a Holosun 507k, is the C&H Adapter plate the only option out there to mount the optic, or does anyone else make a plate for this application? I'm working under the limitation of having to use the Glock 48 MOS as it comes, without milling anything off of it to use the RMRc (?) optic "MOS" cut.

This plate seems to be aluminum, and I'd prefer a steel solution, if possible.
