None of these say they will actually work with the PF9, but I would be surprised if something wouldn't work. I have bought Bianchi before that did not say it would work with my CZ82 or my Ruger P345 and they worked just fine.
You're probably just going to have to go to a gun store or other store that sells a wide variety of holsters and try several (dozen?) of them to determine which you feel most comfortable carrying the gun in. Good luck with the search.
