B. POINT OF FOCUS
Correct sight alignment must be thoroughly understood and practiced. It appears on the surface as a simple thing — this lining up of two objects, front and rear sights. The problem lies in the difficulty in maintaining these two sights in precise alignment while the shooter is maintaining a minimum arc of movement and pressing the trigger to cause the hammer to fall without disturbing sight alignment.
The solution is partly in focusing the eye on the front sight during the delivery of the shot.
Figure 2-4b. Improper. Control of sight alignment is not precise. Distinct focus on target renders sight indistinct. Error incorporated here is the same as Figs 34a and is not as readily apparent.
Figure 2-4c. Proper. Control alignment is precise. Focus limited to front sight only, renders the sights distinct and target indistinct and sight relationship can be controlled constantly.
1. It is imperative to maintain “front slight point of focus” throughout the sighting and aiming of the pistol. The shooter must concentrate on maintaining the correct relationship between front and rear sight, and the point of focus must be on the front sight during the short period required to deliver the shot. If the focus is displaced forward, and the target is momentarily in clear focus, the ability of shooter to achieve correct sight alignment is jeopardized for that moment. Frequently, this is the moment that the pistol fires. A controlled, accurate shot is impossible under these conditions.
2. When the eye is focused on the target the relatively small movement of the arm appears magnified. However, when the eye is correctly focuses on the front sight this movement appears to have been reduced.
C. CONCENTRATION
1. If the sights are incorrectly aligned, the net result is an inaccurate shot. Carelessness in obtaining correct sight alignment can usually be traced to the shooter’s failure to realize its importance. Many shooters will, in the initial phase of holding, line up the sights in a perfect manner. However, as the firing progresses, and the shooter is concentrating on delivering the shot, he often loses correct sight alignment which he attained in the initial phase of his hold. Usually, when the shooter is unable to maintain a pin-point hold, his concentration on sight alignment wavers. An accurate shot is lost because the shooter is thinking of his arc of movement and not the perfection of sight alignment.
2. Another factor which contributes to the deterioration of sight alignment, is the feeling of anxiety which arises over the apparently stationery pressure on the trigger when attempting to fire. An impulse is generated to got more pressure on the trigger, so that the shot will be delivered. When the shooter thinks about increasing the trigger pressure, a degree of the intense concentration required to maintain correct sight alignment is lost. Even if trigger control and the hold are good, the net result will be a poor shot. Sight alignment must remain uppermost in the shooter’s mind throughout the firing of the shot. Positive trigger pressure must be applied involuntarily. Consistently accurate shots are produced when the shooter maintains intense concentration on sight alignment during the application of trigger pressure, while experiencing a minimum arc of movement. Control of the shot is lessened in direct proportion to the loss of concentration on sight alignment.
3. The average, advanced shooter is probably limited in sustained concentration to a period of 3 to 6 seconds. This short space of time is the optimum period in which a controlled shot can be delivered. This concentration interval should be attained simultaneously with acquiring a minimum arc of movement, a point of focus, satisfactory sight alignment, and the involuntary starting of positive trigger pressure. If exact sight alignment is maintained, and the trigger pressure remains positive, the shot will break during the limited time the shooter is able to control his uninterrupted concentration. Result! A dead center hit on the target.
D. THE EYE
The principal difficulties which confront the shooter during aiming are determined to a great extent by the inherent characteristics of the eye and its work as an optical apparatus. All shooters should familiarize themselves with the optical properties of the human eye as explained in Annex II.
CHAPTER III. TRIGGER CONTROL
A. GENERAL
Correct trigger control must be employed in conjunction with all other fundamentals of shooting. The physical act of applying pressure on the trigger to deliver an accurate shot may vary from individual to individual. Proper trigger control for each individual gradually assumes uniformity when the techniques of proper application are mastered. Many shooters, for example, maintain a degree of trigger control with a relatively light grip, while another shooter may use a very tight grip. Some shooters prefer to apply consistent trigger pressure at a rapid rate, while maintaining correct sight alignment. For another shooter, a slower, deliberate application may achieve the same results. An ever increasing number of shooters use the positive approach to trigger control, that is, once it is initiated, it becomes an uninterrupted, constantly increasing pressure until the weapon fires.
Trigger control is of very great importance in producing an accurate shot. When the shooter exerts pressure on the trigger, he must do so in a manner that does not alter the sight alignment, or position of the pistol. Consequently, the shooter must be able to exert smooth, even pressure to the trigger. Furthermore, the trigger must be pressed in conjunction with maximum concentration, peak visual perception of sight alignment and minimum arc of movement.
In order to produce an accurate shot, the shooter must carry out many diverse, but related, actions. Fulfilling this action is compounded by the fact that the pistol is in some degree of motion throughout the period of sighting and aiming. The movement varies according to the stability of the shooter’s stance. Consequently, the sight alignment deviates from the aiming area. Often it will move through the aiming area, pausing only for a short period of time in perfect alignment with the target. It is impossible to determine when, and for how long the properly aligned sights will stay in the center of the aiming area. This difficulty is aggravated further by the fact that the shooter is trying to execute coordinated actions when reflex action seeks to contradict them. Such a situation requires the development of conditioned reflexes, and improvement of coordination.
The coordinated action of correct aiming, timely pressure on the trigger, and the correct delivery of the shot is difficult and can be accomplished only by overcoming former uncoordinated reflexes or by acquiring new ones. Only through constant training and attention to accepted techniques can these new reflexes be acquired. The peculiar nature and characteristics of the human nervous system are covered in detail in Annex III entitled, “Processes of the Human Nervous System Relevant to Equilibrium, Trigger Control and Hearing”.
