I bought a Kel-Tec PF9 two days ago and I took it out this morning to fire a few rounds thru it. On the 10th round I pulled the trigger and nothing happened, then I noticed the firing pin fall out of the back of the slide. I didn't see how it was held in there, I couldn't get it back in. Needless to say I'm a little disappointed, glad I tried it out before having to depend on it. I sent it back to Kel-Tec by UPS, I hope they have decent service and turn around time. I sure like the size and lightness, I don't expect it to be a great shooter, but I expect it to not fall apart.
