So I stopped in to my local gun shop to talk to the owner (I know him well) about doing a transfer for me, when I spotted a poor lonely little PF-9 in the case... I am still not entirely sure why but my wallet is lighter and my pocket is heavier...
Its an earlier production model based on the serial, RB1**. However he had basically stolen it from some jackass and was willing to part with it for a great price, its blued (and poorly at that) with a grey frame. It didn't however look fired, the bore hadn't been smoothed at all and there was no wear on the slide or anywhere else.
After a quick cleaning and lube I headed off the firing range, it fed fine, the only issue was a avg of 1 per mag light strike, which is pretty significant for a gun that is supposed to be a pocket ccw piece.... back to the bench.
Tore it down did a light fluff and buff, polished the feed ramp (even shined up the exposed parts of the barrel a bit), and the dug into the light strike issue.
After removing the extractor I played with the firing pin a bit and noticed a significant amount of drag, and a tendency to want to snag.
Pulled the pin gave it a good going over with some 400gr sand paper, followed by some 600gr for a decent shine. I then took a 5/64" drill bit and ran through the firing pin bore (BY HAND!, no drill needed), at first I could barely get the bit in the bore, but after a while I could get it in a bit... then I used a wooden pencil and a heavy object to convince it to pass the rest of the way through, after that I was able to work the bit by hand and smooth out the bore significantly.
Now to get to somewhere to put some rounds through and see if anything has been resolved... and then I think I might have it refinished... seriously, does kel-tec do any finish work to these guns?
Kel-tec only does repair. And you will want to look at getting the mag release button switched to a metal one, if your early version has one in plastic. Lots of good info on ktog.org
