My vote is for the Kel-Tec P11, especially if you like to really get into your guns and get to know everything about the equipment. The P11 is about the smallest, lightest 9mm 12+1 pistol out there. The polymer casting and machining isn't as smooth as the $500+ guns, but then the price is about half, also. If you do a full-out disassembly and polish everything and then put it back together, you'll have a smooth, reliable subcompact pistol that is in every way equal to others that are more than twice the price. AND, you'll have gained an intimate knowledge of exactly how everything works inside. The P11 is a long-proven design, and has been out for many years, with many thousands of users and the Kel Tec Owners Group (ktog.org) forums has tons of info about them and how to make them even better. I've had mine for over a year and wouldn't trade for any of the others in its size/weight/capacity class. If you want something even flatter, go with a Kel-Tec PF9, but you give up 5 rounds of magazine capacity and only gain 0.20 inches thinner and 2 oz. lighter for the unloaded gun. The PF9 has a lighter trigger (5#) vs. the P11's 8#, but the P11 trigger feels, to me, about the same as my S&W .357 Combat Masterpiece revolver's trigger (smoothed out by a gunsmith), so I don't have any issue with it. In any case, these days, there are NO absolutely guaranteed-reliable pistols out there - everybody's constantly changing suppliers and outsourcing, trying to get a competitive advantage and better pricing. So I go with a U.S. manufacturer (Kel-Tec is in Florida), and put in about 1/2 the money plus a bit of my own time and elbow grease. And I now have a pistol that I completely know and trust.
