I have a Kel Tec P-11 and a P3AT. I had a PF9, but did not like it as much as my P-11. The P-11 holds more ammo, and it fills my hands better than the PF9 did. Also, I have about 800 rounds thru my P-11 without but a few malfunctions with FTF. The PF9 I had was really picky with ammo. It might have just been that particular PF9, but I'll stick with my P-11.
