My personal CCW pistol is a Walther PPK in .380. As others have said, a .380 is a good starting point - I wouldn't go smaller. A couple of things I like about my PPK for conceal carry: It is small, compact and fairly light in weight; Mine is stainless steel, so maintenance is less than a blued steel pistol; The design of the double action and the 'de-cocker' feature are great; It has a 'loaded chamber' indicator that is easy to see and use; The safety completely locks up the pistol until released; It has an exposed hammer that you can manually cock for the first shot, or with the PPKs 'double action' feature - just pull the trigger until it fires. The only thing I don't like is the lack of a 'slide release'. The slide stays open after the last round is fired, but you have to pull the slide slightly rearward to let it reload a fresh magazine. That requires 2 hands. My PPK is very easy to shoot. I don't find it 'snappy' at all in .380. I have 5 mags for mine - and all have the 'extended mag base' for a surer grip. I've never owned a Bersa - but 2 people I know who have hated them and traded them off as quick as they could. That was more than 10 years ago - and both were guys I used to work with - so maybe the issue was with the early Bersas?
