Kahr PM9 (or MK9). My first purchase after getting my CWP was a PM9 and I don't regret it. If you're not going to pocket carry, you may want to consider the MK9 instead.
Oh, and don't get frustrated. Buying guns should be fun. It's definitely addictive. You can always sell what you don't want later. Get yourself a big drawer for holsters also.
