A light emitting module is attached to one of a pair of separable U-shaped metal clamps that can fit around a weapon trigger guard. The clamps have recesses for retaining elastomeric inserts which contact the trigger guard. The inserts are of inexpensive glass-filled molded plastic rather than machined steel so that a greater variety can be provided at low cost and little value is lost by discarding those not needed for a particular weapon. The greater variety provides a better fit with little or no custom shaping and the elastomeric inserts are much easier to shape if an unusually contoured trigger guard is encountered. The electrical cord running to the on/off switch for the module emerges from the module in fixed relationship to the clamps and need not be removed to change the module batteries. A trigger guard mountable laser sight that is more resistant to shock and requires less ongoing adjustment to maintain light beam and boresight coincidence is obtained.

An external laser sight mounting assembly, for rugged stable attachment to a mounting structure having a configuration with potential variations from a norm, the assembly comprising: a laser module for selectively generating a light beam; a first clamp portion coupled to the laser module, and having therein a first recess facing away from the laser module, the first recess having a bottom and sidewalls; index means for providing predetermined relative orientation of a first end portion of the laser module and the first clamp portion; a second clamp portion removably coupled to the first clamp portion and having therein a second recess facing toward the laser module when the first and second clamp portions are assembled together, the second recess having a bottom and sidewalls; elastomeric inserts fixedly received in the recesses in substantial contact with the bottoms and sidewalls thereof so that significant movement of the inserts in any direction parallel to the bottoms of the recesses is prevented by the sidewalls of the recesses, adapted to receive said structure; and tightening means for coupling the first and second clamp portions together and, with the mounting structure disposed between, biasing the elastomeric inserts against the mounting structure; the inserts being formed of a material having predetermined hardness and compressibility characteristics such that the inserts are sufficiently deformable to conform to variations from the norm in the mounting structure configuration, but sufficiently hard to effect a rigid attachment to the mounting structure.
