I'm with the short, maneuverable shotgun if you can't coin up for a proper hand cannon. If you can make them yourself or have somebody make them, load it with rocksalt in the first round, followed by XX buck in the second and subsequent rounds. Chances are, whoever you are defending your home from is going to be long gone after the rocksalt, and you didn't have to kill anyone. Living with the fact that you killed somebody is no fun, even if you were in the right. Which ever choice you make, just make certain that you're better trained in the employment your weapon than you are in the employment of your vehicle. Cars can be replaced......your kids, not so much. My $.02
