Puppy, I personally don't see any draw back to the single action such as the 1911. You practice with it and have mastered it. I however, have not. I practice with double action and am used to that. I am not used to having to manipulate a safety. It is simply what someone is accustomed to. I am afraid in a stressful situation, I will draw the gun, pull the trigger and nothing will happen. This is simply because I have not trained in moving the safety.
