It's a good thing you started your own thread 'cause you could get a lot of response on it. My advice is to get the largest caliber you can handle and conceal, if that is your purpose. A gun that fits your hand and points where you want it to with enough practice. Ideally you should try out a variety of makes, models, and calibers before making your decision. Revolvers are simple to operate but don't carry as many rounds and are slower to reload than a semi-automatic. Only you can decide.
