Abstract
A laser beam generating module is disposed at or near the butt end of a handgun in substantial alignment with the gun barrel. The module may optionally include means for activating the laser which are responsive to the horizontal or vertical attitude of the handgun, means for adjusting the aiming module for accuracy at various ranges, and means for suppressing the laser beam until the user of the handgun is ready to use it. A version of the invention places the laser module at the end of a magazine insertable into the handgrip of an automatic handgun so that the laser module is carried just adjacent the butt end of the handgun. Placement of the laser module at the butt end of the weapon yields accuracy adequate for routine police work, does not upset the balance and feel of the weapon, and it enables the weapon to be carried by its user in its conventional holster. Variations of the invention are described such that the laser module is built into the handgrip of the weapon, inserted when attached to a conventional ammunition clip, and attached to the butt end of the weapon by means of a mounting bracket.
