If you carry IWB with a small gun there are so many options! But if you are set on a pocket pistol; which I think its great to own a pocket gun as there then are not any excuses to not carry at some point. But to the point, if you are set on a pocket pistol; from what you listed I would also recommend the Kahr. You really can't go wrong with it for a pocket gun. As some have said you may look into the CM9 rather than the PM9. It will fit in a pocket better than others you have listed and not only that it really is a quality gun IMO especially for the money on the CM9
