Default PF9 fte and ftf solved

Thanks to everyone who contributed to this forum, i now have a very reliable and carryable self defense weapon i can trust.
By polishing the feed ramp profusely to solve the failure to feed, and then by adding a second extractor spring to the existing one, and then finding a screw that was a bit longer, grinding it down to work, the failure to extract has been completely dealt with, no matter what ammo i use.

For anyone with a new PF9 you will probably experience this issue, if not immediatley then down the road when this spring starts to fatigue. My suggestion is to do the add on. It costs around 2 bucks to get a new spring from kel tec, then go find a screw at the hardware store, stainless steel if you can find it, make sure it is longer than the one you already have, and file it down to the place where it will secure your firing pin and put a small dab of blue locktite on it. More is not better, it will gum up your firing pin if you do. Dont ask me how i know.......This fix will make your gun reliable. I have not had one fte or ftf since i have done this, and i cant count how many hundreds of rounds, and different types of ammo i have used. lead, jacketed round nose, jacketed hollow points, it doesnt matter.

Here are some pics of my kel tec with some fiber optic rods i cut and installed in my sights, and a pic of the extractor "spring" that needs to be doubled up.

Not that difficult at all if you do it with the sights off the pistol. Working on the front sight with it on the gun makes it more difficult than it needs to be.
Get a Spare set of sights, install the rods, then install the new sights.

Here's a great 'How To': Installing fiber optic sights on a PF-9

I used the original screw with double extractor springs. Why the need for the longer screw? Seemed to engage the threads fine.

Some are concerned that the original screw might not be long enough to securely retain the firing pin when using the two spring set up. I use the original screw and it has held the firing pin securely for nearly 400 rounds now, so don't see this as an issue for most, but a slightly longer screw (as long as it does not bind up on the firing pin) won't hurt anything either.

Errrr, this isn't required on all PF9's is it? I recall in my research that one guy even TRIPLED his springs. I believe on that thread there were some responses of folks with thousands of rounds through their PF9's with still just the one spring. I hope that is the case otherwise why isn't Kel Tec installing double extractor springs from the factory?

Would be nice to have some more recent posts of folks who are bone stock with the one extractor spring and having zero issues.

around 1,600 rounds with one spring. never had a problem with extracting. my problems have been light firing pin strikes and off center firing pin hole. took lots of work and free parts to fix the problem. but i never had any problems with extracting. i feel if you do a good f&b of the inside of the barrel, working more on the hood and deep in the chamber you will fix the problem.
