Noob question here. I have a generation 3 model 19 with original, unmodified sights. I am confused about the proper way to aim. Below are 3 different pictures I made, with the pistol aimed at the red "bulls eye"... which one is correct? In picture #1, the sights are exactly under the bulls eye. In #2, the sights are halfway covering the bulls eye. In #3, the white dot on the front sight is covering the bulls eye. I know the real answer to this question is "take your gun to the range and find out what works best for you." I am just trying to get a base proper technique to work with when I do go to the range.
