Love #2.
I used to argue with the old man. Old man: "Why BytorJr, do you need to carry?" BytorJr: "Well old man, if I knew I needed a weapon, I would not go. Or, if I did go, I would not go without a long gun (preferably an SCAR or M-4, if I KNEW I was going into mortal danger). I'd also request an AC-130 gunship in a racetrack pattern over me old man; along with some A-10's just for good measure. But, since I'm a civi, I'll take a pistol since that's about the thing I can legally carry in any state I visit. Thus, the point "old man" is that hope I can get back to wherever my long-gun is. So "old man", I carry because I cannot predict the future. And I'd prefer to carry a rifle, but since I cannot, I carry a pistol.
