You may other reasons why the firing pin broke, puddled oil under its rear slide area, burrs, misalignment. It shouldn’t break and 99.9% of them do not.

I read a lot of forums and I geuss they redesigned it an the new ones are good an hold up I’m still waiting for Kel-Tec to respond

right, they are only $4, order one or two. If you want warranty they’ll want it back no doubt.
I have a spare, on hand, for $4 why not?

When I bought my PMR-30 it did not even work, wouldn’t pick a round from the magazine mostly, misfires, slide hard to pull back, thumb slide release took two thumbs and way too much pressure to disengage the slide. Took it home and deep cleaned it, checked it out etc.
Under the firing pin was a puddle of nasty oil, thick and alien to that area, debris in the slide’s paint, yes, kel-tec painted the slide areas in a non-clean environment, filed down the corner of the slide catch.
I have a long detailed post here with links. Its worth the couple hours to go over it.
I went from 40% plus jams, misfires, etc to nearly zero now, I can unload 25-30 round magazines without issues, using several different ammo types. Get the mCarbo feed ramp and magazine fix, those two items will make a big difference.

here:

  • I cleaned out the slide channels with a fine angled file, upper and lower, not much, just enough to clean out the channel and get the slide to move properly.
  • Filed the catching corner of the release, this video shows it. https://youtu.be/RmHb45vH8yA?t=130
    I used a steel diamond nail file and took several passes, reassembling each bit and tried it until I had it where I liked, now it is very nice, a bit of pressure to retain and releases like a Glock.
  • Pulled the firing pin and found a puddle of nasty oil in the channel, cleaned that well. Took the firing pin and used 600 grit Emory cloth and polished the flats and cleaned the edges.
  • https://www.youtube.com/watch?v=iNZuuvJOBdY and removal - https://youtu.be/Y5hUXEdQZl8?t=103
  • Reassembled with NO oil , this is a blowback, so the firing pin area is quickly contaminated by blowback, oil attracts dirt, so no oil. (Oil like a Glock, just the slide rail areas and minimal)
  • I ordered the Mcarbo “Enhanced magazine release” to remove that .040" inch drop of magazine at chamber/pick area. If you observe the slide in action, it only catches about 25% of the next round, with the Mcarbo mag catch it goes to about 33%. https://www.mcarbo.com/kel-tec-pmr-3…e-release.aspx
    Changing it took about 3 minutes with no disassemble of lower receiver. Take out screw, pull pin, pull factory mag release, use 1/16" tubing (about 2" long) to hold spring ends together, reinsert the new mag release with spring in rough position, use hemostats to assist in holding spring, and install pin and screw(s).
  • Also order a good loader, I got the loader by American Speedloader, or the lula pmr-30 speed loader is highly regarded as well. Hand loading over 20 is hard and causes damage to shell casing very easily, use a good loader
    Nest loader: https://www.ebay.com/itm/PMR-30-SPEE…72.m2749.l2649
    Magula loader: https://www.midwayusa.com/product/1021153869?pid=896872

It’s working really good now, pretty much at zero percent failures. I am adding the stainless feed ramp and will polish it, I think the poly factory ramp will no doubt get a groove in time due its very nature of the material, so that is for prevention more than current resolution of feed issues, but it will help with different types of ammo.

This all took a few hours, but it is as reliable as any auto I have and fun to shoot, I love to fireball out of the muzzle!

So far, I’ve shoot 200 rounds through it, without the new ramp and zero failures. And used 3 types of ammo, 2 CCI’s and Federal.

I think Kel-Tec needs to read how to fix their guns with your ideas and suggestions. Thanks for the information I’ll definitely be trying it out and hopefully get it trustworthy again.

thank you, but it also took quality parts from mCarbo to make it work as it should

Anyone ever run into a problem on your Kel-Tek sub 2000, where your trigger jammed up
when you went to put it back together after your MCARBO trigger kit? It seems that as I tighten the feed side handle section. Had anyone got a possible cause and available solution, I thought about an additional shim
but I don’t have a clue as to what thickness to use.

I saw somewhere like what you are describing and it says to loosen the three screws along the rail and near the bolt and try again I think it was on a tandom cross video of trigger install

yes, had this issue, and it did seem the grips were too tight, but with OEM parts, since I have not torqued them down so much, but a shim would be good, not sure how the mCarbo pin set would help. The description doesn’t show them as longer. But, another thing I did is clean out the groves for the trigger as shown in video here:
