HK P7 PSP. You can still get the German surplus pistols for close to your price range if you look around. It is a single stack 9MM (8+1) with a very nice single action trigger. Very safe to carry, thin, a bit heavy but with a decent holster no problem. In fact I carry mine with a regular leather belt (not a stiff or heavy gun belt) on a cheap Uncle Mike's nylon holster designed for a small auto. It fits perfectly and works really great.
