Yeah, obviously the Q5 Match is in a whole different league and price range, and designed to be a competition gun, but for a carry/duty pistol, the PDP is really good. I'd say it's really a toss-up between the VP9 and the PDP, depending on what features one cares about/doesn't care about. But in the $530 price range, I haven't handled anything else that comes close (and I've handled quite a few). If the price on the VP9s came down, it would really be a toss up. I'll take either one over a Glock any day.
I hear ya about not needing another 9mm - I was just telling myself that again last week.
