Abstract: A handgun sighting system that adjusts the intensity of a lighted front sight based on the ambient light conditions. A sighting rib on the handgun includes an electronic circuit having a power supply, a light emitting diode (LED), a photocell, and a reed switch. A holster for use with the sighting system includes a magnet therein. Return of the handgun to the holster brings the reed switch of the weapon in close proximity to the magnet and deactivates the LED and the electronic circuit. Withdrawal of the handgun from the holster activates the LED and the electronic circuit. The handgun sighting system automatically adjusts the intensity of the LED in accordance with changes in the ambient light conditions, as measured by the photocell, to provide an optimal sighting presentation for the shooter.
