I second the kel tec p3at. It's cheaper than the ruger.
http://www.mouseguns.com/semis.htm I actually wish I had one. I bought the pf-9 which is awesome. But its to much int he middle. My other concealed carrys are a USP 40c and S&W M&P .45 midsize. So for the small bugout gun i'd much rather have super small. And that is absolutely the p3at or ruger. Like I said Id get p3at for the price. If price doesn't matter itd go kahr 380, ruger then p3at last.
