I second the PPK. It's slightly larger than the more modern polymer .380s, and is a little heavier. However, it absorbs a lot more of the recoil than the lighter pistols due to this as well. There is an article I read about it recently that talks about how if you do have to pull your weapon, which hopefully you never do, the PPK looks like a gun, where the newer, smaller pistols get lost in your hands. As a lot of situations are stopped by the mere sight of a pistol, the PPK is easier to recognize. It is also a very accurate little pistol. Amazing what a 3.5inch fixed barrel can do. I carry mine during the warmer months when I can't carry my USP. I have about 1200 rounds through it with 0 hiccups so far. I carry it IWB in a Theis holster, as it hides a little better that way.
And you get to look like James Bond.
