its like this, you are flinching. and it only takes a slight flinch to be way off target. it is a mental thing, that is what you have to overcome. one thing i tell people that sometimes helps a lot is to count 1-2-3 when pressing the trigger, of course you will not get past one before the gun goes off. but it makes you concentrate. always put it in your mind that you will not move that front sight off the target. hope this helps,,,,,,,,,,,,,,
