Several years ago there was a company that advertised in Shotgun News that altered M1 Carbines to fire the 45 Win Mag cartridge.
There is a company now that makes a "chassis" that takes a 1911 reciever, and thus uses 1911 mags to make a 45 ACP carbine.
Once upon a time a buddy of mine bought a bunch of Rising full auto guns from a Police Dept, in 45 ACP. They did not have that great of a reputation on the conditions of WWII, but for us they never malfunctioned and were a hoot to shoot.
