When you look at your front sight, look for something specific about it. Look for a scratch, a defect, or a peculiarity. It really helps if you have something that will force your eye to use a “pursuit” movement (This is like dialing in the zoom on a microscope to achieve perfect focus on just one cell.) This will prevent you from looking through your sights. Keep your focus and acuity on that peculiarity of your front sight throughout the entire firing process.
