Everyone knows that a 9MM is superior to a .45
.......... Two years ago this month I purchased a Ruger 9mm PC Carbine. At that time I just thought it was neat and wasn't considering home defense, as I already have handguns, shotguns and a good supply of ammo. Then this year I suddenly began the "what if" thought process concerning the PC Carbine. I suppose 9mm would also be useful unless we're talking body armor.
