Well I got my second replacement PF9 from Kel Tec and I finally got one that shoots 50 rounds without jamming.
As some of you may know I have been critical of Kel Tec for almost a year. Having bought a P32, P11 and PF9 and all three were problematic. If I read this I'd ask, why did you buy three when you had problems from the first. Well they got consistently worse. The P32 was resolved by Kel Tec 'selling' me a fix for their poor design. The P11 was nice about everything but trigger and reliable. Well after about 300 rounds it's about 95% reliable, and, after doing the trigger thing from the Kel Tec forum the trigger is actually ok. Now the PF9 which I had high hopes for was atrocious. It couldn't fire 14 rounds without a jam. Two trips to Kel Tec and I got 50 rounds through the latest version.
I've learned a very important lesson I'll share with you guys. If you buy cheap expect cheap. I bought a Kahr PM9 for less than I paid for the three Kel Tecs and now they are of no use. If I can find a buyer, their gone. All three. The Kahr has had no failures, versus numerous failures from all three Kel Tecs. The Kahr is very accurate, versus keeping the shots on the paper with all three Kel Tecs. The Kahr is fun to shoot. The P32 is ok, the P11 is acceptable, the PF9 is punishing. The Kahr shoots anything I feed it, reloads, +P, hollow points, whatever. The Kel Tecs are very finicky.
I hope this helps someone. No need to argue with me. I'm not coming back to this thread, I've heard all the pro Kel Tec, and I don't doubt what others have experienced. Documented above is what I experienced, for what it's worth. Add your comments for others to read, if you want.
