Got the call yesterday from the CMP. Sent the email instructions to my FFL. They mailed me back asking for make of the 1911. I was unable to answer as there are no guarantees with the CMP.

I looked at the handgun roster and saw both colt and Ithaca were listed but couldn’t find Remington rand.
Just trying to get ahead of this in case my ffl starts telling me this isn’t MD legal.

They’ve been great for other transfers but I’m guessing that don’t have much experience with the CMP.
Any insight would be much appreciated.

It's on the roster, US Military 1911A1. Or something like that. You or the FFL can check the roster.

Not needed anyway,"The Handgun Roster is a list of handguns manufactured after January 1, 1985 that have received final approval for purchase in Maryland by the Handgun Roster Board and that are not otherwise prohibited by law."
