Glock remote switch - Streamlight Contour Remote Switch for TLR Weapon Lights

Very easy to attach to the weapon light. It replaces the old manual switch cover on the rear of the light. Will take some getting used to while shooting as it changes the pressure you are applying with your fingers, but it makes using the light a whole lot easier and more intuitive. Less thinking about manipulating the little paddle switch. Mine is attached to a light with no laser so I can't speak to that.
