With the Gauss Compact S, the underbarrel weapons are key. The gun is balanced out by the reload time, so you need to use the underbarrel weapon in the event of a needed reload in a firefight. I suggest the Underbarrel 'nade launcher for LA's, and the under barrel shotty for CQB. The underbarrel smoke 'nade launcher is just for if you need sudden cover for storming a building, no real use IMHO.
