Sight alignment is the relationship between the shooter’s eye, the rear sight aperture, and the front sight. The front sight blade is centered and flush with the rear sight aperture. “Equal Height; Equal Light”.
In order for the bullet to hit the center of the target, the shooter must aim the pistol and give the barrel a definite direction relative to the target. In theory, accurate aiming is achieved when the shooter places, in exact alignment, the rear sight with the top and sides of the front sight and holds them in alignment in the aiming area. A requisite for correct aiming is the ability to maintain the relationship between the front and rear sights.
When aiming, the front sight is positioned in the middle of the rear sight notch with an equal light space on each side. The horizontal top surface of the front sight is on the same level as the top horizontal surface of the rear sight notch. A RELATIONSHIP OF SIGHTS. It is necessary to be acutely aware of the relationship of the rear sight to the clearly defined front sight. Normal vision is such that the rear sight of the pistol will be as nearly in focus as the front sight. Some shooters may be able to see only the notch of the rear sight in sharp focus; the outer extremities may become slightly blurred.
“The top of the front sight is even with the top of the rear sight and there is an equal amount of space separating the front sight post from the sides of the rear sight notch.”
