Twenty years ago, when I first taught my wife to shoot, I taught her on a 1911 in .45, because that's all I had. That was a mistake. (Ignoring, for the moment, all the other mistakes I made that day, like teaching my own wife.)
Now I start people on a Ruger 22/45, then do the standard progression, 9, .38, .40, .45.
