I personally carry three weapons in my vehicle/on me (depending on where I am and what I am doing)
They range from .40 S&W, .308, and 10mm. The forty is used as my back up back up/last ditch/uh oh gun. My 10mm is my sidearm, and I strongly consider this caliber to be offensive. It has NO defensive properties. It is fast, semi-big, penetrates rather deep (read:soft armor), and transfers energy well. I would never have a 10mm as a defensive caliber, due to over penetration. This is a no-no for civvie rich enviornments.
Next is .308, which isn't available for a pistol unless you have a T/C.
