I've had my PF9 for a couple of years now. I rarely carry or take it to the range. I clean my firearms when I buy them and every time I take them to the range. My PF9 jams after about 60 rounds. The third time at the range, the pistol jammed and I could not pull the slide back. I ended up taking it home and after some effort I was able to disassemble it. The underside portion of the barrel that holds the assembly pin sheared off. I have never shot anything but factory ammunition almost exclusively Winchester 115 gr and some Blazer 124 gr. Kel Tec lived up their reputation for customer service. They replaced the barrel and polished the feed ramp. It took some time, but I can't complain about the service. I seems fine now, but I just don't have any confidence in this pistol. It's a shame as I really like the features in this pistol. With the steel side clip, this is extremely easy to conceal and the accuracy is fine.
