1. Recoil Anticipation. Recoil anticipation is the most common problem for firers in achieving a consistent shot group. When an individual first learns to shoot, they begin to anticipate recoil as a natural reaction to the firing of a weapon. This reaction may cause the firer to tighten their muscles during or just before the hammer falls. Firers may fight the recoil by pushing the weapon downward in anticipating or reacting to its firing. In either case, the rounds will not hit the point of aim. A good method to show the firer that they are anticipating the recoil is the Ball-and-Dummy method. When conducting the Ball-and-Dummy Method, the coach loads the weapon for the firer. The coach may hand the firer a loaded weapon or an empty one. When firing the empty weapon, the firer observes that in anticipating recoil they are forcing the weapon downward as the hammer falls. Repetition of the ball-and-dummy method helps reduce recoil anticipation.
2. Trigger Jerk. Trigger jerk occurs when individual's see that they have acquired a good sight picture at center mass and "snaps" off a round before the good sight picture is lost. Firers must train themselves not to rush a shot until they have proper sight alignment (front sight is aligned with the rear sight), sight placement and apply consistent pressure to the trigger.
3. Heeling. Heeling is caused when a firer tightens the large muscle in the heel of the hand to keep from jerking the trigger. A firer who has had problems with jerking the trigger tries to correct the fault by tightening the bottom of the hand, which results in a heeled shot. Heeling causes the strike of the bullet to hit high on the firing hand side of the target. Coaches may be able to identify the firer twisting the pistol as they apply grip pressure. In most cases, the discussed shooting errors can be corrected if the firer knows and applies correct trigger squeeze techniques.
