Follow-through occurs when you keep contact with the trigger and only let the trigger release to the “reset position” between shots.
In order for your shot to reach its intended location on a target, a shooter must have sight picture and alignment. Sight alignment is the symmetry between the front sight and rear sight. Your front sight should be in the exact center of the rear sight, at the same height of the rear sight. Remember the old adage: equal light, equal height.
