After reading up on the PX4, then checking them out at my friend's LGS, and then renting and shooting one of their guns, I ended up buying 3.
F types. Full-size .40, compact and sub-compact 9.
They are nice shooters. (The 9's; I haven't shot the .40 yet, but will soon.)
FWIW, the Sam Andrews MacDaniel II IWB holster for the FNP http://www.andrewsleather.com/macdaniel2.htm
and the Talon Tactical Kydex saddle for the FNX (not on the page but can be ordered) http://www.talontactical.com/index.p...hk=1&Itemid=64
fit the PX4.
Sam Andrews is a friend of mine; so is Mike at Talon Tactical. They make good gear, and it will fit the PX4, so there you go.
