I've been testing it for reliability and one part of the plan has been to shoot it at Oakdale USPSA. Last year I shot a Glock 30 and it functioned flawlessly.
On Thursday the Kel-Tec failed miserably.......multiple FTE'S in each course...badly wedged cases in the chamber. The previous week it was almost as bad... and Monday I ordered a new (free) extractor kit from the factory in Florida.
ON the Kel-Tec forum http://www.thektog.org/forum/ 2 suggestions are change ammo / stop limpwristing.
I did change ammo for the last course to premium hollowpoint self defense ammo and fired 8 properly ejected rounds.
I was shooting Winchester White Box...and the word on the Kel-Tec forum is AVOID WWB (and Remington economy ammo)...(runs fine in the Glock)
On the way home from Oakdale I bought 200 rounds of Federal Champion 115g 9mm for the next round of testing at Bills.
I pulled the extractor and everything looked fine...a little bit of carbon but not much...the 'frankenbolt' was not loose.
The purpose of this gun is to fire anywhere from 9 to 21 rounds in a life-threatening emergency and that's it. It's as light and thin as possible and cost under $300....
I could be badly limpwristing but I'll rule that out next trip to the range....I'm hoping it's just ammo. Plan B is to send it back to Kel-Tec ( 8 week turn around

The word from the Kel-Tec factory is that most of the PF-9's they get back ARE NOT defective but the shooter is limpwristing....
Anyone else solve a PF-9 FTE problem ???
