If you are REALLY talking a pocket gun in 9mm, you only have one choice: Rohrbaugh R-9
I agree. The other 9mms out there might be small..but they aren't really pocket guns. Some people can get away with carrying something like a PF9 in their pocket...but while I would consider that to be a very compact gun, it really isn't designed to be a pocket gun. A pocket gun to me is something that goes in any pants pocket. You don't dress around a pocket gun. You dress around carrying a full size pistol. What good is a pocket gun if it only rides ok in one of your pairs of pants? What happens when you wear something else? Heck, at that point I'd rather have something in a holster. It's really either a Rohrbaugh or you'll probably have to go .380.
