I would look at the Sig Sauer pistols, if you're looking for something to carry. I have a buddy down south there that has 3....one in .45, one in 9mm, and one in .22 for his woman.
The 9mm is a a P226 Blackwater, the .45ACP is a P220 Carry(He has a CCW Permit), and the .22 is a Mosquito.
He swears by the SigArms stuff, he's never had a single misfire or jam, and I know the 9mm and the .45 have both had at least 500 rounds put through each of them.
Personally all I've ever played with was a Luger chambered for .22LR - lots of fun to play with, but wouldn't be a practical carry piece.
