When aiming your handgun all points of your body should face in the same direction. In the bladed stance your body should be some degrees off  from the line of your pistol sights. In the natural shooting position, all body points will mirror the sight-line. Either position requires that all body points agree in direction. Body points are feet, knees, hips, shoulders, and head. Check to see if you twist your body while in your  firing stance. Muscular tension is a physical force against perfect sighting. Check yourself in front of a mirror.
