ABSTRACT:
An internally mounted laser beam gun sight suitable for use in automatic pistols is provided by replacing the conventional recoil spring guide rod with a hollow tube having substantially the same exterior shape and dimensions, but containing a laser beam generation module, batteries and an on/off switch within its hollow bore. In a preferred embodiment, the hollow tube has two portions which are movable with respect to each other. A first portion contains the batteries and a second portion contains the laser module. An insulated bushing containing a central electrical contact is located between the two portions. In the preferred embodiment, the central contact forms part of an internal electrical switch which is activated by relative motion of the first and second portions of the guide tube to turn the laser beam on and off.
