I have a PF-9 and love it. It shoots 1.5" groups easily at 15 yards and is absolutely reliable with Winchester silvertip HPs. I carried it in the front pocket of my cargo pants in a nemisis holster, until I lost so much weight that I shrunk out of 'em and went back to my jeans, which don't have as large pockets. It became more comfortable to switch to a belt slide holster, but a hot day sorta requires me to OC.
This minor inconvienience is not sufficient to send me back to the P3AT, but I will say that if it wasn't for the extended mag floorplate it came with, it would be pretty unpleasant to hold onto when it goes off. It fits my wide hand fine, but my wife doesn't like the narrow, deep grip proportions or the grip texture, and kept her P3AT.
