"Trying to come to grips with my G20, I happened upon something which may apply to you too. I realized that when I tightened the lower part of my hand, the lower 2 fingers, that pressed the lower end of the Glock's backstrap into the heel of my hand. This sort of took up some slack in that area and prevented pulling shots low. YMMV, or it might work for you too. "
