My personal preference is a 1911 model 45 but if you like the Walther PPK then take a look at the PPK/S which is a 380. It's smaller, lighter, easy to conceal and if you load with hollow points it has sufficient stopping power. Just remember that if you have to pull it -- shoot, don't talk and if you have to shoot, keep shooting till he is on the ground and stops moving. If you empty the magazine it can be a good argument that you were " in fear for your life " and panicked.
