Well, you can choose to carry the plastic mouse gun and go wrestle with bulldogs, Rottweilers and whatnot as well as multiple badguys, all of whom will take you by surprise. I'd bet the house on a well-conditioned, well-motivated Pit Bulldog or Rottweiler over you/me/him/her and any .380 "micro pistol" any day...
"Necessity is the plea of every infringement of human freedom. It is the argument of tyrants, it is the creed of slaves." ~ William Pitt, 1783
