I am in agreement with the thumbs forward style. But I have found myself on my Butt, shooting upward using the famous hurry up and shoot this guy before he shoots you stance. When possible you should use proper techniques. It will help even if you find yourself in the Butt shooting position. It's difficult to take everything into account, it has to be second nature. And you must get to a point where no matter what happens you are able to adapt to the situation. No one was around when I started shooting ,other than family, so I picked up a shmaydray of techniques and oddly enough they weren't much different than what works and is taught today.
I guess given enough time a man figures out what works and what does not, But it sure is much easier today when you have the type of guys like the ones in here to help you save years of trial and error. Sam ,9,Tuner, and others, will save you a lot of grief if you practice what they are telling you.It just may save your life someday. That 1/4 inch difference might make the difference in weather the guy can fire another round or his frontal lobe has been detached from his muscles.
But again if you found a system that works for you then use it, just don't be so stubborn that you refuse to try something new. If you can put 10 rounds in the bullseye at 50 feet, in 10 seconds, then stop reading and keep doing wht your doing. You may just want to pick up your speed. But otherwise you are very likelly to survive a gunfight. If you can't then try something different. Shooting paper is different because you can correct you aim on a stationary object, Not so with moving objects, it just happens too quick, You would be better off shooting quail or pheasent, when you don't know where the bird is and it just takes off. Try it with a pistol if you are under the impression that you are that good.
My bet would be that you don't hit 1 bird. That's ok most folks including me would have to be lucky to do it, but we never stop learning. If you get 2 in a row with a pistol, then you are very good, and need no assistance.
