Get some good AZoom snap caps and practice firing at a dime sized spec on your wall. When you think your doing better, lay a nickle on the top of your barrel and practice some more. When you go to the range, shoot at 5 yards, again at a dime sized spec, and concentrate ONLY on the front site. I read about this method in a Clint Smith (Thunder Ranch) article in American Handgunner a few years ago and it transformed my shooting from "******" to "really good". Flinching is no longer even a thought.
