What is the best small gun in fallout 3

It really depend on your taste on fire arms in any range small medium(rifles and what not) or large, there isn't really a best gun in the game(well there is) but there is always a better gun than the next one in dps/damage. the gun i mainly go with is the Chines Assault Rifle or the The Terrible Shotgun anyways the best small gun in fallout 3 is the Callahan's magnum.
