If you scored high in spatial reasoning and mechanical aptititude, get that fancy autoloader you've been drooling over in the magazines -- just be sure you get to know it real good before you learn to depend on it.

Two of my autos have never had a malfunction in many thousands of rounds. Yet I've seen a revolver that routinely bound up after five rounds. Lesson: shoot the heck out of any gun you plan to stake your life on. Regardless of action type, never just assume it is reliable. (BTW, I do agree that on average revolvers are more reliable than autos. I've found autos ranging from jamomatic to flawless and everything in between).

Yup, a big exception to every rule.... The first .357 I ever bought new (S&W L-frame) was a jamma-matic. Years later, I read in an old magazine that Smith and Wesson had recalled it!

It worked pretty good when I got it back -- but I'd never trust that sucka . . . .

I took my little Keltec 9MM to a range and fired three boxes of shells through it, and experienced a consistent "nosedive" jam when the clip was down to four rounds.
I bought a couple of new magazines and haven't had a jam since. Its size makes it a great little carry piece.
For under the seat in a vehicle, the new Keltec SU-16 would make a great little defense rifle, if it is reliable. It uses standard M16/AR15 mags (.223 cal), and folds in half for storage. The forestock folds out to become a bipod, and there's a slot for an exra mag in the shoulder stock.
