Do you mean placing a laser in the forearm instead of a light?
If so, honestly, I'd rather have the light. Anything in the center of the cone will be hit by the SG. No need for the laser at all with the light on an SG. Unless you are going for the elusive "take down the hostage taker with a head shot from a slug" move.
Otherwise - no idea what laser would work best for that.
