I saw in the nut'n'fancy review that the kel-tec will jam up if you fire from a prone position because the mag gets pushed up into the action too far... To me, that is a deal breaker for any kind of defensive arm.

The mini is a good choice I suppose, but after having owned one for a year, I can honestly say that any half decent AK (or even SKS) will serve you just as well, if not better, for a lot less $.
