We have guys here who shoot PPC or Bullseye with PPC9s, and they know lots more than I do. These guys are serious, shoot teensy groups, and should be here.
But as I understand, the PPC9 is about the same pistol as the Target Champion.
FWIW, I bought a 5" PPC9 exactly because of its' accuracy; they ship with a factory test target of under an inch at 25 yards. Mine did that with the Federal 9BP load, which is regular off the shelf ammo. This pistol fits in a standard Safariland paddle holster and uses factory 5906 mags (thick bumper pad), which is what I use when running our qual courses with it. I don't know anything about PPC matches or the equipment they use.
