OK, I appreciate the comments and thoughts, but here's the thing,I know most pistol engagements are self defensive and actually happen within 3-7 feet, 21 feet is your minimum draw against a knife attack and as for the actual shooting its gonna be instinctive, but there are other scenarios that occur. I never said that I had some sort of superhuman judgment cause I practice, I practice so that I become a better shooter, does not make my scene interpretation any better As for the PPC comment, I never said that it would not help you, I merely said, that just cause you shoot it does not give you better judgment, however I would say that due to the fact that PPC teaches excellent fundamentals that you would have higher chance of hitting the target, call BS if you want, but we just differ on opinion, here is the other thing, I said I simulate shooting the environment which I'm in, and no its not fisheries and Oceans,lol. As for the where to shoot, when to shoot, I'm talking situations, your a on a crowded busy street with tons of bystanders, or your in a hospital, your gonna start busting rounds off that's not risky at all(yes I'm being sarcastic)..., yeah duh center mass..but what if the only visible mass you have is a calf, or a arm, that's now your center mass,as for ammo management, you better have your reloading down pat, especially if your carrying a revolver and you know you have only 12 rounds in total. oh and by the way if you hear click it will probably be the last thing you here, you never wanna hear click. You never want a empty gun. So if I'm off in thinking those things are important, well, I guess I have to disagree with my learned colleagues on this site.
