I've seen mixed reviews of the PF9 in the past, and I was cautious about buying such an inexpensive carry gun. I made sure to test mine at the range for several months before trusting it enough to carry it, and I am extremely happy with it.
I had only 1 jam when the gun was brand new: one of the magazine followers got stuck inside the magazine body and didn't push any more rounds up. I took the magazine off and trimmed a little bit of excess flashing off it. The gun has never jammed since then.
Speaking of excess plastic flashing, the very tip of the trigger had a little pointy piece that I removed with a little piece of sandpaper. After that, my finger is happier.
I carry the PF9 every day, and I even sold my Glock 26. This feels so much slimmer and lighter. The trigger pull is rather long, but it doesn't stack towards the end. It's smooth, but I can't shoot it as quickly as a single action gun. Because the gun is so light, the muzzle does rise quite a bit more than most 9mms. It isn't a gun I shoot very many times at a given shooting session, but I practice to keep proficient, and I move onto a more heavy gun for range time.
I'm very happy I got this. It's so wonderfully slim and light, that carrying is comfortable. I would recommend this to anyone who finds themselves wanting a smaller 9mm for carry rather than just shooting for fun.
