I have owned several SA autos before, but they were mainly target guns. I've got a SA auto on order, to use as a CCW. Which means I need to spend some serious time training in the proper use of the 1911-style thumb safety. I've heard some people say that you should train to flip the safety off as soon as you clear the holster. But this would seem to nullify some the benefit of having a safety in the first place. I mean, if you trip and fall down while carrying the pistol, or are fighting an attacker for possession of the pistol, then having the thumb safety engaged helps to keep the pistol from going Bang! before you planned on it. And drawing the pistol is not necessarily the same thing as being ready to shoot (if a mugger threatens me with a knife, then hopefully just displaying the pistol will solve the problem). What are the various schools of thought on when the thumb safety should be disengaged? My first thought, admittedly from target shooting, is that the safety should only be disengaged when the sights are on target, and you are actually ready to shoot. However, I've never had tins cans shoot back at me, so I'm happy to listen to those with more knowledge of actual combat. Having the pistol not go Bang, because you forgot to disengage the safety, could also also ruin your day (under some circumstances).
