I have a PF-9, and I have no problem with HP. I use CorBon DPX, but if you are worried about it, you can always go with PowRBall ammo. Feeds like ball, works like HP. Also there is an EFMJ (expanding full metal jacket) load out there, but no one near me seems to have it, so I haven't tried it. You can use +p ammo in the PF-9 sparingly, (but not +p+ I think) so speed and penetration shouldn't be a problem.
