If it's legal to build one from an Essex Frame, down in Mass, that's what I recommend doing. My 1911A1 is one I built that way. Ross's niece sure did like it.
Yes, perfectly legal although few FFLs here will order a frame that isn't on the "List". Legally, MGLs do NOT recognize frames as a firearm . . . our definition is something that is complete and ready to shoot.
Reminder for new folks (or some of the "OLD" members with short memories
): Do NOT list dealers who will order frames here. If the AG finds out who they are (and there are folks who scan forums for such info), his gestapo will terrorize them into refusing to do this legal deed.
