DISPOSITIVO DI MIRA LASER ARMI DA FUOCO MANUALI

A cylindrical shaft has a forward and a rearward end portions and a longitudinal axis. The shaft also serves as the recoil spring guide for the gun. A diode and collimating lens are located at the forward end of the shaft, the lens collimating a beam of light from the diode along the longitudinal axis of the cylindrical shaft and parallel to the barrel of the gun. Electrical power for the circuit board is supplied through a conductive rod running along the longitudinal axis of the rearward end portion of the shaft and through the gun slide stop which is conductively isolated from the gun frame. Conductive trips are mounted on a non-conductive plastics panel in the first side of the gun handle. The strips in conductive communication with a first switch in the base of the gun handle. The first switch controls current from one of at least two sets of batteries mounted in opposed sides of the handler conductive strips between the sets of batteries and the metallic magazine carried in the handle of the gun. This complete an electrical circuit when the magazine is in the handle and interrupt the circuit when the magazine is removed from the handle.
