<p>Handgun front sight 140 has an elongated, rectangular body with a light pipe 21 inserted into the open space between the rear opening 141 and forward opening 142. The base of the front sight is slanted to raise the proximate end relative to the distal end. The rear sight 120 has a body 102 with a circular opening for centering the target. A compass ring 60 fits inside the circular opening. A pair of light pipes 116a, 116b in the body of the rear sight are aligned with 90 and 270 degree points of the compass ring to establish an imaginary line across the diameter. The front light pipe is centered along that imaginary line.</p> |
