Abstract: An automatic handgun with a laser sight which may be adjusted in elevation is disclosed. A laser beam source and mechanism for adjusting the elevation are all contained within the guide rod chamber. At the front of the guide rod cylinder an adjusting ring is turned clockwise or counter-clockwise to rotate a slotted cylinder having a spiraled slot therein in which rides a finger of a cam rod. The cam rod is moved forward or backward to move a cradle to tilt a yoke holding an optical prism through which the laser beam passes. The beam is bent depending upon the tilt of the prism. The automatic handgun is thus provided with a laser sight that may be adjusted for elevation and all of the components of the sight are contained internally of the handgun within the slide return chamber.

Abstract: A laser gunsight for semiautomatic hand guns is disclosed. The laser circuitry, diode and lens are contained in a cylindrical shaft which replaces the usual recoil spring guide. Electrical power for the sight is supplied from either of two pairs of batteries mounted in plastic panels in the gun handle. Current is carried through conductive strips embedded in the plastic panels, The slide return and cross bar which are electrically insulated from the gun frame, and an electrically insulated longitudinal pin in the cylindrical shaft. An on-off push button switch on one side of the handle makes or breaks contact with the conductive strips in the plastic panel. The circuit is completed through the gun frame and magazine which is in conductive contact with the batteries when the magazine is mounted in the gun. When the magazine is removed for loading, the circuit is interrupted, which in combat situations serves to assure that the laser is not inadvertently activated and the user's location revealed.
