I'm looking for a good revolver to be used mainly for home protection, but it may see a little concealed carry time. I'm looking for a DA/SA 9mm/.38 SPL/.357 MAG with about a 2 inch barrel. I'd like it to hold as many rounds a possible too. Suggestions? How good are the .38 SPL and .357 MAG for stopping power? I've read that the 9mm has one of the best lethality rates of any bullet. That, combined with a smaller recoil, less flash, and availability of rounds, made me decide on the 9mm for home protection. Are the .38 and .357 comparable?
