Yes, I know. I”ve seen quite a few at gun shows and at some places like Southern Ohio Guns. You are usually looking at staring over $1200 and go up from there.
Several companies (including Colt) make WW2-spec .45 autos now. Some of them are really close to the WW2 versions, and are much cheaper than the originals. There are also new-made M1 carbines and M1 Garands, although the Garands don’t seem to be that well-made and have some function problems.
