One thing that no one has mentioned is that the M-1 Carbine is a great gun to hand to someone who isn't really into guns, as a loaner in a crisis situation. If the wife isn't into guns, the carbine is OPTIMUM. After all, that's pretty much what it was designed for in the first place.
When I had better eyes, I could get 5 inch groups at 100 yards, using a big black target, the front post, and cheek weld rather than rear sight.
My only beef on the carbine is that the safety is tiny, and I have bobbled it a few times under stress.
Obviously, it lacks the power of larger cartridges, but Audie Murphy didn't have a problem with it, (when a track mounted Ma Deuce wasn't handy.)
