Recognizing that it's all in your head. Flinching when shooting is almost entirely mental and is the anticipation of and the response to something unpleasant such as recoil or the gun shot noise. Neither of these two things will hurt you.Fire your gun.ther people try to stop flinching by concentrating on the front sight and saying over and over while squeezing the trigger front sight...front sight...front sight.... Concentrate on the front sight. I tried this and it did help a little. If repeating a word in you head doesn't work try shouting the word in your head.
