If you don't know how to use firearms well, don't get them. If you do know how to use them, I suggest something like this. A .22 will get you small game and you can store a lot of ammo for a small cash outlay.

If you want something bigger, get a 12 gauge shotgun, perhaps a pump like a Remington 870. A 12 gauge slug will know down any large game in North America and the shot shells can be used to take ducks, turkeys, and other birds.

But I repeat: do not get firearms if you don't know how to use them and aren't willing to learn IN ADVANCE. And if carrying a gun will make you feel 8 feet tall, covered with hair, and invulnerable, don't get one -- you'll get yourself killed if you do.
