Mossberg 500 12ga., Hunting (long barrel, bird, buck or slug) & Close Social Work (short barrel)
357 Maximum Contender, scoped, medium and big game and medium-longer range Social Work
.22 Rimfire, rifle (10/22, or Nylon 66) OR revolver (Single Six, or S&W Mod 34) for small game, entertainment and last ditch Social Work.
Note I did not consider CCW or really long range rifle Social Work. In the first case it is a specialized case IMHO, in the second it is probably not going to be realistically possible for me.
