If you like the PPK style pistol, check out the Bersa Thunder .380. For around $199, it's a GREAT little gun, that isn't prone to problems feeding like the PPK.
Despite it's low price, it's excellent quality for a little gun. I bought mine right before Christmas. Shot about 400 rounds through her so far, and she keeps going. I think I had ONE FTE in all of that.
It's still slender, being pretty much identical in size to the PPK. The 7 round magazine keeps the rounds higher in relation to the chamber, so they are pushed in, instead of up, when feeding. Has the decocker/safety, and it includes what the PPK should have, an external slide catch/release.
Accuracy is good. Trigger has a little creep in both DA and SA, but is still pretty light in SA, and isn't unbearable in DA.
MUCHO bang for the buck. You could get two for what you could get a PPK or one of those Sig clones.
