1911 extractor too long?

[FullEffect1911]

I have a suspicion that this has been covered once or twice, however after searching through the sea of 1911 questions I've determined this may not be to easy to find.

Anyway, I just got a new Springfield 1911 loaded, it's very nice. However I did change the extractor immediately with a Brown Hardcore due to my past experience with Springer extractors.

The Hardcore had no proper beveled edges and had to be fit with a new FP stop, strange since my last Hardcore extractor was nearly a drop in part.

So I fit it up and tensioned it. It worked fine during firing. However now I have the 1911 apart and rechecked the tension to make sure it's still good. It is not. The extractor has seemed to lose it's tension.

I can retention it, but I have another problem. The extractor claw is contacting the beveled extractor grove of the case. I understand this is a no no, however there isn't anything I can do short of just removing the whole claw to prevent that from happening. The OEM springfield extractor just seems to be a tad shorter in over all length.

Are Brown hardcore's longer then normal? Is there a different extractor I should be using? I could use a little help on this one. And the most important question... is a little bit of contact normal, especially considering that the gun was operating normally?

Okay, so i just re-tensioned the extractor and did the recoil springless thumb feeding 1911tuner test and everything worked fine. However now it seems like all of my extractor tension is gone again just after a few magazines worth of the tuner test. Is this even possible unless it's a junk part?

After tensioning the extractor to more that seemed necessary, it works in the tuner test and seems to be maintaining it's tension.

I did take in the middle pads as per tuner's instruction. Is the whole point of doing this allow me to use more tension then normal and still allow the 1911 to function properly?

I think it got it worked out, i'm just curious about a lot of this stuff and I figure this is the best way to learn.

What brand of ammo?

Did you check it with any other brand?

At any rate, it is not uncommon to have to file off some of the forward bevel, or relief angle, to fit a new extractor. They are made overly long to allow for variations in slides.

First, dress off the relief angle or foreword bevel to clear the case bevel.
Second, dress off the sharp tip of the hook until only the inside of the extractor is in contact with the cartridge rim.

The point of the hook should not rest on the bottom of the case rim groove.

The foreword bevel should not touch the case foreword bevel in front of the rim.

After all that fits right, file & polish the three feed and ejection clearence bevels.

winchester and federal cases will contact lightly at the case bevel.

The hook was already reduced to about what tuner suggests (I can't remember the dimension currently).

I'll see what else i can do with it as per your suggestions.

So I was just reading a post between jammer six, 1911tuner, Fuff, and Dave Sample, and i got to thinking.

Aside from Jammer having the same issue I am (though to a greater degree), and unless I am wrong, stock springfields are shipped with a 9mm sized extractor. Well is a 9mm extractor shorter then the .45 ones? If so springfield's specs for the slide may call for the short 9mm one... Just a thought anyway.

Springfields use a 9MM firing pin. The extractor is not specific to 9mm.
And also the later S.A. firing pins are not even standard 9MM but slightly smaller.
