Anyone see this.
Is this normal. Is this something you have to replace often?
To me this should be hitting only brass, and steel should be the winner.
Yes, how many rounds?
No

I happened to have one sitting on my desk, with thousands of rounds through it. I only fire brass though. Steel case ammo might be a different story. Looks fine, but is a bit dirty.

There are always more in the pipeline...
THANKS.... yep I cleaned it, polished it and it did not look too bad and put it back together.
I am disappointed in KAHR...They never got back to me... I sent them a request.
The part is $16 I recall... So I am going to by a new one. The extractor is scoring or making the rim of the brass. Since I reload this is not good to have these deep scratches in the rim....
Good eye, Greg. I was going to say the same thing. You should never put a round in the chamber and then drop the slide.

Thanks for the input Gents, but that is speculation on your part I can address. I have never dropped a round in the chamber. I know better.
I only go into battery one way and one way only, I lock slide back, insert magazine with bullets (brass case), release slide. For more data
I shoot standard 115gr FMJ for practice and premium LEO Federal or Speer JHP on rare occasion. Also FYI in 500-600 rounds I have never
had a misfire... So I am doing something right, rough edge to extractor or not.
UPDATE, to Kahrs credit they are sending me a new extractor with a return envelope to send old one back for analysis.
I well informed in mechanical engineering and metallurgy by education and profession. Brass will not do this to hardened
steel.
Could it have been that way from the factory?

Thank you for the clarifying how you chamber rounds gmcjetpilot.
Not having the part on hand to examine closely, we must speculate given the evidence in your photos. Your photos suggest to me that there is damage to the edges of the extractor, but I can't tell definitively if the edges are deformed or chipped.
I've not tested an extractor to verify whether they are hardened or not. Have you? I'd very much appreciate hearing your results if you have.
For the sake of argument, let's say that it is hardened.
One way knife makers test hardened blades is to press the flat of the edge against a brass rod. This can result in a deformed edge, chipped edge, or an unaffected edge.
I'll not argue that the edges of the extractor are thicker than most knife blade edges, but given the correct conditions (enough force, shock, etc.) I think it plausible that the edges of the extractor could react in a similar manner.
With that in mind and from the location of the damage on your extractor, I still believe this is could be caused by rounds feeding ahead of the extractor (and I'd be checking my pistol to see if it was push feeding).
Then again, I may be way off base with the above. So, kudos to Kahr for sending the part and I'm pulling for it to fix your issue.
Regards,
Greg

I say that puppie needs to soak in some gun cleaner for a few days and scrubbed with a stiff wire brush. If the rest of your gun looks similar, maybe just throw the whole thing in there and let it soak. With the already tight tolerances of the Kahr, your clogging the drain so to speak.
