CM9 Extractor is Hammered (Pictures) - Any One See This Before

Interesting post cjb. I'm not totally on-board with with all you wrote, but will keep it in mind. However, I do now tend to agree with you that the extractor in question was deformed when new. I say this because after reading your post I decided to look at this from a system view vice just looking at the part. Doing that and given how the extractor sits in the slide (had to go take a closer look) I don't see how anything could come into contact with that trailing edge with enough force to cause any damage there.

BTW, what I'm not on board with is that while, as you point out, many modern extractor systems have a built in tolerance to being snapped straight over a rim, I still believe it is not a good idea to get into the habit of dropping the slide of a controlled feed pistol on to a chambered round. I'd also point out there can be other things to consider: I.E. Springfield Armory advises not to manually load rounds into the chamber of their XD series of pistols and I'm guessing that this has to do with the LCI they use.
Anyway, thanks for the lesson Oh, almost forgot, I still believe steel can be damaged by brass.....But, y'all can believe what you want.

CJB must be right. My desk still isn't clean.

LOL, I just posted along the same line.

Desk cleaning is available..... But youd needa put up with my accent.

Could it have been that way from the factory?

Hmmmm?

Fair enuf!

Hey in a friendly way, have you ever wondered if all those controlled feeding cycles are actually that, or have some of them, in cases where the bullet has jumped forward a bit from the magazine... being pushed in by the extractor instead of the boltface? Food for pondering.

I must hate cleaning my desk, since I have always kept it a mess. With only one part to look at, it is hard to know what happened. It could have been in a bunch dropped on the factory floor and run over with a fork lift.

I don't recall seeing a photo of an extractor that looks quite like the OP's. I had my MK9 slide detail stripped today, and it looked like the photo I posted earlier, but maybe not quite as dirty.

When operating any machine, I do try to manipulate it in a way that causes the least damage or wear that is still conducive to what I am trying to do with it.

This has been a great discussion of the Kahr extractor and did get me thinking in a bunch more detail about how it functions and what its environment might be.

Thanks!

It wouldn't surprise me if some did get push fed. I have pushed rounds as far forward as possible in my CW45 and they all still fed up under the extractor, but that's hand racking them. I have a little Casio camera that can do 1000fps, might have to set it up and do some experimenting.
