The rail system on the S&W Sigma Series does not allow a laser to be mounted because the grooves do not extend all the way to the end of the barrel. This adapter, by LaserLyte, turns the rail system into a Picatinny/Weaver-type rail system, allowing a laser or flashlight to be mounted. It fits snugly into the grooves on the rail system of the S&W Sigma Series and two screws tighten down the adapter to the rail.
