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?
A gunfight is not the time to learn new skills.
If you ever have a real need for more than a couple of magazines, your problem is not a shortage of magazines. It's a shortage of people on your side of the argument. -- Art Eatman
