Stovepipe Issue with Super Carry Pro

My Super Carry Pro HD has started to have a stovepipe issue.
It's about 1-2 times per 100 rounds, doesn't seem to matter what ammo I use.

After some reading & think I may have it traced to a worn extractor. The tension still seems fine (able to hold a live round with slide removed from the frame), but the lip seems worn & is shorter than the extractor on my Kobra Carry.

My recoil spring is the Wilson Combat Flat Spring & only has about 6000 rounds on it. The pistol has about 6800 rounds on it.

I swapped out the extractor with my Kobra Carry & will visit the range today or tomorrow to see if that resolves the issue.

The ejector looks fine & is not loose or broken.

Any other ideas for troubleshooting this issue?

If the Kobra Carry extractor resolves the issue, should I replace the extractor with an Ed Brown part, or stick with Kimber, or consider Wilson Combat?

Chick, that sounds like a good starting place to me but I'm no expert.
If it proves to function perfectly with your transferred Wilson part, I would probably order the Wilson part as a replacement. But that's just me.
Good to see you posting, long time no see.

Thanks. I'll update once I've been to the range.
Good to 'see' you again too! I'm trying to work less & have more time for stuff like this...

Range visit update:

Ran 100 rounds through it with the Ed Brown extractor -- had 1 stovepipe & 2 failures to extract. Not the results I was looking for....

I cleaned the pistol & gave it another close inspection -- can't see any marks in the barrel, the Kimber extractor passes the 'tension test'. Not sure what else to try at this point.
Today I should have some time to pull the extractors from all the other 1911s in the house & make some comparisons.
Any other suggestions?

Maybe a small one. You're only discussing 1/2 of "slide timing."

I would also check your ejector. While I'm not a gunsmith, I know some guys who replace that with a differing ejector (why, I'm not sure) as part of a reliability package.

It could still be the extractor. There is some useful info here:

Thanks for the link. Looks like I have another range trip in my future.

You are probably fine with an EB extractor, but another thing to check is whether the rim of the case is touching the bottom of the notch in the hook. If not the tip needs to be reduced a bit.

This trick is the exact thing I referred to here in another post for the modification covered in the NRA book "The .45 Automatic Pistol". It covers the file mod required to the extractor hook to give positive, reliable extraction of the fired case and deposit them all in a nice concentric circle at 4:00 to the shooter.

Easy mod with demonstrable results.

It does sound like your extractor is letting the empty go too soon-your all on the right track.
