Michigan Ammo (Mike P) offers a 9mm round that's specially built for that gun. It comes as either "Factory New" and therefore useable for Distinguished or as "Reload" for everything else.
This round is the most accurate I've seen in the S&W PPC9. In fact it's the round used by Performance Centre on the test target that came with my gun. It has reduced recoil and the price is quite reasonable (not that much more than it costs me to load my own when all is said and done).
