I dunno, after reading a ton of stuff and out of all the classes I have taken by squared away guys, I never considered point shooting. I get a flash sight picture but to me if you want hits on target, you use your sights for anything over 5 feet.
There are certain things the body begins to do after the release of adrenaline in hight stress situations auditory exclusion and tunnel vision are 2 of them. Can It be trained out? Yep but I found it requires a lot more training than most average people do and most seem to default to their lowest level of training rather than rising to the occasion.
What's your background, mil, leo, competitive shooting/3 gun, etc?
