While I’m not an expert in shooting a pistol (although I did get that medal in the Navy) I have found that treating the barrel as an extension of my index finger has been pretty effective when shooting on a combat course. Certainly lining up the sights is the most accurate method for an aimed shot, but after practicing the point and shoot method for a while I found that it is pretty good for hitting very near center mass out to 15 yards or so.
Thirty years ago at a Navy pistol range we were doing a basic courier pistol qualification and one of my buddies couldn’t hit the target. The instructor had him safe his weapon and just point his finger at the target and then closely look down his finger to see where it was pointed. After that he began to think of the revolver as an extension of his finger and his scores improved dramatically. While that will not result in many hits in the X ring it does allow you to put effective rounds in a man sized target very quickly.
We all like to think of ourselves as rugged individualists. But when push comes to shove most of us are sheep who do what we are told. Worst of all, a lot of us become unpaid agents of whoever is controlling the agenda by enforcing the current dogma on the few rugged individualists who actually exist.
