Focus on the Front Sight
The name Front Sight comes from a shooting technique that focuses on just that. In this technique the most important thing to focus on is the front sight of your gun. As pictured above you should have the front sight completely in perfect focus while the target is blurry. This idea is coupled with learning to have a correct stance and correct grip on your gun. Once your stance and your grip are right you place the front sight on the center of mass of your target as your finger enters the trigger guard and begins to take the slack out of the trigger, align the sights perfectly as you transition your focus to the front sight. Establish a crystal clear focus on the front sight as you smoothly PRESS (not pull) the trigger until you receive a surprise break. For me the difference between me pulling the trigger and me pressing the trigger with an even pressure and letting the pressure build until a surprise break made an enormous difference in the accuracy of my shots.
