I'm not a fan of kel-tec. Had one a few years ago I bought for CCW, but had sooo many feeding problems with all but one or two types of ammo; sent it back to KT a couple of times for adjustment; it would work ok for a couple of mags worth and then start misfeeds all over again. Would only shoot hardball, and then only for a bit. JHP and TC were jams constantly. Got rid of it and have carried a Firestar P9 ever since.
As far as self-defense guns for non-enthusiasts...JMHO but...double action wheelguns only....simple and easy to shoot under stress and that is all you have to know. A medium frame SW in Ti or Sd is perfect for the casual shooter...no jams, misfeeds or safeties; just point, pull the trigger and BANG. 38's for practice, 357's for the real thing.
Tried to teach my wife on a Glock (the simplest of DA autos) she got so confused she never shot it; loves her 4" barreled Python and will shoot it (quite well) all day.
Unless someone is going to shoot a lot, I recommend they stick with wheelguns.
