I have a PF9 and I love it. I have never had any problems and never did a "Fluff & Buff". It just hasn't been necessary.
It is NOT a range gun, a target gun or a "let's go plink" gun. It is a Self Defense gun, period. Small, light, reliable, long, stiff trigger, no external safety and very easy to conceal. It makes a great concealed carry weapon.
You hear a lot of bad things about Kelties, mostly, IMO, from people that think a cheap gun is somehow no good. I have 2. Looking for a third. Yeah, they are cheap. Does that mean they're no good? NO. And the company WILL stand behind them. And after you get a couple hundred rounds down range, they'll smooth out and be just another tool that you carry and can use with confidence.
Yeah, I like mine.
JMNSHO &, of course, YMMV
