My advice,worth every penny you are paying for it, is the old suggestion: Carry the biggest, most powerful gun, with the most rounds, that you will ALWAYS carry. If that is a 5-shot J, so be it; just carry a few speedloaders and/or speed strips along with it. If it is a K, L or N, so much the better. But that 629 in your safe won't help you when three skells decide to carjack you at the Phillips 66 station.
