I had lots of FTE problems with my P32. KelTec sent me a new extractor which helped, but then one night at the range the slide cracked near the ejection port.
The next morning I called KelTec, spoke with the shop manager, and he agreed we should just call the gun a lemon. I drove it over to them (they're in Cocoa, I'm in central Florida), dropped it off, went to lunch, and came back an hour later. They'd built up a new gun for me, and they let me go onto their range and run 200 rounds through it. No problems.
I've had it for 10 years now with no more problems.
I'd say their quality isn't always the best, but if you have a problem they will make it right.
