Sig Extractor damaging brass

[Jeryray]

I am uploading 2 photos, one is starline nickel brass damage from sig P226 extractor. The other is the actual damage to the brass (nickel).
I have reloaded federal, speer and others, seems the starline is the only one showing this. I have 4 or 5 sigs, they all seem to do this.

Starline does not have an answer, called sig, they said no warranties on re-loads.

I get it, I am under sammi specs, less re-coil that factory. Been reloading with dillion 650 presses for quite some time.

I may modify the extractor a bit.

Any thoughts?

Any thoughts?

Are your other Sigs all 9mms??

I've never noticed anything like that with my (P220) Browning BDA .45

Remember the primary purpose of the extractor (and everything else) is to operate once with each round. Its nice for us when they are "reloader friendly" but they are under no requirement to be.

Does factory ammo run no issues? I'm no expert and not a handgun guy--but I see a problem with cartridge chambering/firing properly--like it's recoiling back into the extractor upon firing. I'd figure out the basics first before choosing elective surgery.

I have 4 sig 9mm, 2 sig .45.

.45 are all ok.

I think it's the starline.

Going to get my calipers out for serious measurements.

My old eyes may be deceiving me but what I see is damage to the the case bevel indicating the extractor is too long. You should be able to push the cartridge flush against the breechface. The extractor should not prevent you from doing this. If it does, the common fix is to carefully file the front of the extractor to eliminate it making contact with the bevel.

The first picture below shows an extractor that is not too long. It does not make contact with the case bevel which allows the case to be pushed back flush against the breechface.

The next picture shows an extractor that is so long that it will not allow the cartridge to be pushed back flush against the breechface. Shooting the pistol with a too long extractor will result in damage to the case bevel as seen in the last picture.

Great, Dremel it is. Should be ok to take a little off, then I will smooth, polish and either paint or blue.


Thanks

The extractor part or the installation could be wrong in the pictures. If you try to remove metal from the top of the hook to make the cartridge bottom on the breech face, as it should be, you probably won't have any hook left.

File may be better than Dremel in this case.

OK, Done polished and blued.

Will try new starline next week and check that nickeled brass.

Problem is, my other 9mm sigs may have to be modified as well.

I'm having trouble understanding the logic of modifying the extractor if the problem only exhibits itself when using starline brass--could you not in the process be making the gun only functional to starline brass (assuming it's successful)?

I have over 5k starline. Extra extractors 5 or 6.....

Extractor groove bevels and extractor groove widths have tolerances. For 9mm Luger, it is 25°-35° and 0.035" to 0.045", respectively. So, your Starline may simply have the steeper bevel slope or be close to the narrower end of the groove width, or some combination of the two that gives the end of the extractor less clearance than your other brass did. That said, the extractor does appear to have a lot of space between the inside of the hook and the breech face. I would measure that space with feeler gauges or wire gauges and ask SIG what their specification for it is.

OK, will do. I did get to the range tonight. It's much better. About the same as my 229 Leigon. Other brass has no damage. It's the bevel alright.
I'll run these a few times and see. for now it's a work around. Sig goes nuts unless you have factory ammo.....

I can't tell for sure, but it looks almost like the rim itself might be bent (?).

I should have thought to suggest standing a Starline and one of the unaffected cases up side-by-side on a flat surface, then backlighting them so you could get a visual comparison of their profiles.
