If you don't feel safe with a .45 on your hip, and a 9mm on your ankle . . . . . well, let me ask two questions: (1) Does the next gun absolutely have to be a handgun? (I'm thinking 12 gauge with slugs); and (2) Can you bring friends (preferably carrying rifles) along?
I'm a lawyer, but I'm not your lawyer. If you need some honest-to-goodness legal advice, go buy some.
