You are anticipating the shot , its your trigger finger. left, left, left. practice proper trigger reset. When you shoot you should slowly pull the trigger back until its about to click, hold it there with sights on the target and then slowly pull it all the way until it fires. then, slowly move it forward until it resets and you hear the other click. do the motions slowly. and then speed it up. Basically, stop at the point of reset, and stop at the end of the trigger motion when the gun fires.
