ABSTRACT:
A sighting device for a weapon. The device forms an integral part of the handgun and projects a laser beam onto the impact point of the intended target. The device includes a laser assembly that is preferably disposed adjacent the front of the trigger guard of the handgun. In one preferred embodiment, a laser and laser drive circuit are mounted on a flexible circuit board to accommodate movement of the laser with respect to the laser drive circuit during sight adjustments. Preferably, the laser drive circuit comprises MOSFET devices in analog mode which use comparatively low power. A switch assembly is integrally disposed in a crotch formed between the trigger guard and the handgrip. The power supply may be disposed in the bottom of the handgun's magazine which is in electrical contact with the laser sighting device.
