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.
Yea, I’m aware of that too. I’m a collector of WWII stuff. It’s more important to me to have an original 1911 rather than a repro. I’ve even seen some nice replicas of certain firearms, but I prefer to have an original in firing condition.
