Crazy question - in a SHTF world, does it make sense to standardize so everyone in your group has the same handguns and ammo? I was thinking, if my group has circled the wagons, hunkered down, and has to engage in a fire-fight, wouldn't it make more sense if we all had, let say, 9mm Sig 226's as opposed to Tom shooting his H&K, Dick his Sig 229, Harry his 357 revolver, and Maggie her pink 1911? Wouldn't it make more sense for Tom, Dick, Harry, and Maggie to have all 9mm 226's and as much ammo and as many of the same magazines as humanly possible? I use Sigs only for illustration sake and because I love Sigs. But the standard weapon could be whatever floats your boat.
