It isn't so much WHAT is in your hand as it is how you TRAIN with what is your hand. If you can't detect, assess and engage the threat from the standpoint of being behind (BG has already begun the attack) with your choice of weapons system be it auto loader or revolver it's a moot point. This includes getting out of the holster and delivering rounds on target while moving to cover or getting some distance from the attacker. Being able to engage threats from under a vehicle, through a windshield etc. The possibilities are endless. We spend too much time choosing "the best weapon" and use too little time training with it. I include myself as well. I should be out shooting now. As a matter of fact I think I will.
