Walther PPS.
In my opinion, this is the best overall concealed carry gun on the market today, hands down. Dimensionally, it's about the same size as a PPK, but instead of firing a .32 or .380 -- both marginal cartridges at best -- it fires a 9mm, and is capable of handling the +P loads in that caliber. Thanks to the low bore axis and good ergonomics, the recoil is not at all excessive, despite being a lightweight, compact pistol, and the pistol is thinner in cross section than any comparable gun. Some of the Kahr pistols are comparable in size, weight, and caliber, but Kahrs have a spotty reputation for reliability that Walther doesn't have. I have personal experience of this, having owned a TP-40 that couldn't be made to run reliably after two trips back to the factory (and the shop I bought that gun from has stopped carrying Kahrs because of the number of guns they've had to return to the factory for service). Finally, the gun has a versatility unmatched by any other compact gun, thanks to the three different magazines available with it. The 6 round mag fits flush with the short grip, which allows only a two-fingered grip on the gun, but maximizes concealability for when this is needed. The 8 round mag, which has an integral grip boot at the base, makes the grip nearly as long as a full size pistol, allowing not only increased ammo capacity, but maximum controllability, and is ideal for when heavier clothing or other circumstance permits carry in this mode. In between is a 7 round mag, also with a grip boot, that makes a perfect compromise between the two: the grip is short enough that the weapon will disappear under all but the lightest of clothing, but just long enough to afford a three-finger grip. And you get all this for a very reasonable price -- about the same as a brand new Glock. This pistol's compact size, good ergonomics, and excellent controllability make it ideal for every concealed carrier, male or female.
