I've been carrying my P3AT for a while now and after several hundred rounds it's still holding up just fine. I want something with a little more punch that's not much bigger, though. Most of the time my Sig is just more gun than I want to lug around and there's no way that I can carry it when I'm at work because of my uniform. The PF-9 looks like a good choice. Does anyone have any experience with it?
