Both are well broken in. After more thought they both were working fine until they didnt. Kind of like OP. So i am thinking that the extractor sprimgs weakening is the issue. I am going to strecth them a tiny bit and see if they improve. That should confirm its a spring issue.

 

[silverback]

I going to try yo do thibgs in stages. Tonight ia going to clean extarcor area again. Lightly polish extractor amd slot it resides in with fliz and qtip. Slightly strech spring one. Hopefully test them out at range tomorrow. Anyone have a 1022 extractor spring to test fit it.

I cleaned and lubed my gun, I took it back out, not as bad but still way too many jams. And it was ejecting the rounds practically onto the table. My malfunctions went from a majority of cross case blockage, to parallel case blockage, with the empty cases on the left hand side. Which leads me to think it's got a lot to do with the extractor.

And to top it off my elevation screw backed out and my shots were going high. I just did it back down, and it backed out again. So tomorrow I'm going to loctite the grub screw, and do a full breakdown clean and polish. Kel-tec is sending me springs since I've got multiple iterations. What I think I'm going to do is take two springs and intertwine them, and give that a try, if my polishing and deep cleaning doesn't do any good.

Good info. Jusy finished cleaning.mine. man that spring is uber small. Still this is an elegantly simple design. Cant wait to hear your results

I'm going to warm up the ultrasonic cleaner and break the bad boy down as much as I can in the slight area.

Broke it down and ultrasonically cleaned the bolt, firing pin, spring, slide, extractor, spring, and pin. Inspected everything and I noticed some burrs on the extractor edges. I took some 600 grit wet sandpaper and gently smoothed it. I also smoothed the trunion and bottom of the slide. There was very little abrasion on either the trunion, or slide but I figured what the heck.

Reassembly was a snap with a little grease to hold the spring in place. DONT BE AFRAID TO DISASSEMBLE THE BOLT! As you know I'm partially paralyzed and if a basically one armed man can do it, you can.

One of my biggest faults when doing this stuff is not documenting with photographs as I go to show what I find. While reassembling the thread protector I noticed a tremendous amount of lead build up. That proved to be probably the most time consuming portion. I didn't have any solvent to take the lead out.

Additionally, while at the range I noticed some of the mags didn't want to feed bullets. I would get one round, the slide with cycle, but no bullet in the chamber. I'd look in the chamber area and have to smack the bottom to the magazine to get it to feed. Well tonight while expecting my magazines I noticed that some of the extensions, that are 3D printed, we're sitting kind of cockeyed, and I could literally flex them back and fourth, quite easily. I removed the back piece that allows you to slide the magazine off, and with very little effort it just came off the magazine body. Checking on my mags, I have six total with these extensions, five out of six easily came off. I actually have one still in the wrapper that I can check to see if it is a normal occurrence or if they change once they were on the magazines. Yeah every one of the extensions that are installed, have loosened up and come off easily. Bummer! That might explain his design change. If you've got the original style extension, I strongly encourage you to check to ensure that they have an opened up on you. The material he is using for the 3D printing will flex with any heat. So if you set your magazines on the bench at the range and it's in the sunlight, guess what? I'll try to start a new thread tomorrow with pictures showing what I'm talking about. I'm missing two of my factory base plates. But I've got one more place to look in another range bag. Yeah I'm pretty disappointed.

In any event you got a lot accomplished, hopefully you'll find the base plates.

From the beginning of your thread, your problem sounded alot like the same symptoms I had 2 months ago. Seems you found the same 'burr' in the extractor slot. Since gently removing that burr, I've had no more problems.
I've wondered why this burr didn't cause any problems until after ~ 500 shots. Perhaps the burr was not from the factory, but from the action of shooting. A tiny bit of hard debris may get wedged between the extractor and the guide slot, and wears in the restriction somehow???

I now test/push the extractor 'hook' and firing pin to check proper return action after each cleaning and before each shooting session. Very small movement, but when mine was failing, the extractor would not move sideways without lots of force.

Someone mentioned a stronger spring or doubling up the extractor spring as a solution for you. When clean with no dirt, the extractor feels like it has plenty of return tension. I think too strong of a spring could cause the extractor to not open enough to catch the cartridge rim and cause similar failure issues.
I agree with your encouragement to others that this is a very simple process, Just be very careful to control that itty-bitty spring, and not loose it.
Since fixing this issue, my P17 has had ZERO problems with every kind of ammo I have tried.

here is a link to my posts about this:

Stove pipe fail to eject...solution

My perfectly preforming new P17 started having problems on 3rd day of shooting. Using the same ammo, CCI HP mm 36gr, Aguila 40 gr SE, and REM 40gr Thunderbolt, that had preformed without any issues I started to get 2 - 5 stove pipe partial ejections with each mag. I had gently cleaned after...

I would not hold your breath on getting parts, but by the grace of Keltec.

Keltec changed their parts policy some time ago. I’ve been unable to get a buffer for my CMR for months as they will not sell it. They want a licensed gunsmith to sell the parts to and do the service or to mail it in for warranty work.

My local shop’s smith can’t seam to get the parts either… but I’m not convinced he is trying to hard.

Total pain as I specifically bought my CMR with their parts policy as the deciding factor as I wanted to do a bunch of work on it.

I wouldn’t expect new arms to get many new parts available to order. Only item Keltec deems user serviceable. That list does not always include consumable parts.

Keltec’s reputation for having a good parts policy is historic and currently tarnished.

I hope they didn't lie to me when they said they were sending them out to me. But I do have to send the magazines back to change out the springs, I couldn't get them to send those.

To be clear I’m not saying that they lied. I’m saying you have been “graced” that they made an exemption from their policy or that they intend to sell the part online anyhow.

Unless they have changed the policy, you must be lucky (an exemption made), or see the part on their site to order it.

I know myself and another user has had a hell of a time getting CMR buffers that need to be replaced from normal use.

I don’t want to hijack the thread but there was a speculation on parts availability and I am speaking to that.

For whatever reason any time any one mentions that Keltec changed the policy a bunch of people come out of the wood work to counter the narrative with examples that don’t actually counter the narrative.

Frankly the policy change should be a sticky as I am sure their historic policy is selling units to customers soon to be disappointed. I say this as a disappointed customer affected by this policy change after my purchase.

Well i took both my p17s out today. I cleaned them thoughly. I numbered the mags. First gun had tons of issues FTF, FTE AND STOVE PIPES.
I brushed the bolt and ran a bore snake in barrel between each mag. I started having some issues on second weapon. Then i realized that most of my issues were related to the mags with extension on them. One mag in particular kept feeding rounds nose up or the slide would not pick up a round.

As an experiment i only loades 16 rounds in all the mags.

What do you know 98 percent of issues disappeared. I had a couple of rounds that stove piped but you could hear it was a weak charge.
Couple of rounds stuck in chamber. Usually federal rounds.

I am going to find my old base plates and restore to original configuration. Bummer found all but one. Anyone want to trade an OEM p17 mag base plate for an extended one?

Next range trip i will concentrate on which gun is having stuck case issue.

I think with even a weak charged round you would get complete ejection but maybe there isnt enough speed to get slide to move back far enough.

I liked the extension on the base plates and the extra rounds but it's not worth reliability issues. So 16 rounds will be enough for me. I am not in the mood to tinker with these extended mag base plates.

I am still interested in seeing if a slightly stronger extraction spring might make the gun even more reliable.

I am going to super clean the guns again and lube with Sentry tuf glide dry lubricant.

These guns are so much fun and accurate.

Oh and that one mag that had the feeding issues on every round. I am sure it is out if spec. I will call kel tec and get it replaced.

Tomorrow i am finally going to get the chance to sight in my cp33 16 rifle.

 

[Tnronin]

Took mine out after the clean. Nope. Kel-tec sent springs and an extractor. I'll change those or tomorrow and try it Monday.

 

[Tnronin]

Got the spring changed. Noticable difference in strength. I also put in the new extractor just for giggles. 100% for two mags. 2 different types of ammo. My buddy said he notice a definite change in ejection between the two. His .22 ammo had more power. Given the choice of ammo I'll use the pricey CCI but sometimes you gotta use junk.

Here are a couple pics. At first glance I thought the were using a longer spring, the coil count was the same. Well during the reassembly I had to pull a new spring out that I was attempting to use and it was compressed to the same length, BUT it was stiffer.

On a side note I had to deal with a rear sight issue, I'll start another thread with pics etc later.

It's like this this thing unspooled at once.

Good to hear. I just got off the phone:
+1-800-515-9983

No issues getting replacement springs and new ejectors. I also have a newag base plate coming in. I misplaced one.

Very pleases pleased with thier service

I have always found that the more spare parts you buy...just in case...is a sure guarrantee that you will never need any spare parts. I have Buckmark, Makarov, BHP, Beretta, AR, and Land Rover parts out the wazoo...never seem to need any.

LOL that might be why Kel-Tec have started selling the parts!

On a side note took the wife this morning and she put 6 mags they it warning up to the G19 with no issues.

I had that problem with the rear sight when i got my first p17. Kel tec sent me a new one. I immediately put blue loctite on the screw and made adjustments. No problems after that. Did the same with the second one. I found that was turning the adjustment screw to aggresively the first time. You have to be gentle with it and it doesnt require too much adjustment to get it dialed in.

Took my daughter and her guns to the range today. P-17 required very little pressure to turn that setscrew.

I'll shoot them an email on this.

Last night i was crusing through sime p17 videos. I came across one where the guy was discussing friction issues
So i did some hand polishing with very very good results. Oh i also realized i need to start cleaning this gun after each range session or at least before the next one.


Any way i polished the sides of the slide , under the slide , the opening of the slide that the barrel comes through and the top of frame. I also lightly polish the polymer edges along the frame thay.may come in contact with the slide. The metsl portion of the frame needed this baldy. I took both guns to the range and what do you know i only had two failure to extract. those rounds needed to be pushed out of chamber via cleaning rod. They only happen on one gun.

I am going to fillowing CMMG procedure of buzzing the chamber as it may help.

I think this week i will use a dremmel to give those areas a polish .

Great results with my old extractor springs and extractors.
