Since I have no real idea, I'll stab at it blindly.

Perhaps that long length of metal would be too "springy" as the extractor moves away from centerline as the cartridge enters under the hook. With the pad there to stop the outward movement, it would essentially make the "sprung" portion half the length.

IDK...it would seem there is a distinct purpose to have it there.

Good question! Hope someone with more experience and 1911 "edumaction" than I will be able to shed some light on this!

I was thinking that also.

But that just raises a new question. If the outer central pad is going to rest against the outer side of the extracter tunnel, then why remove the inner central pad?

I'm not trashing them at all, I still have one with 10 15rd mags and 2 hip and a shoulder rig for. Carried it for months until one came up in the gun locker I could have but mine still got shot in matches under minor scoring for about 4k rounds, still 98% being shot and looks like it's pretty much out of the box.

I'm obviously older than you, big heavy bullet works better than a small and light crackhead rounds. The 9 and 40 are still mainstays but the serious boys use a 45. Now the 40 is a good round but why would I buy one because of the fbi? Give me a 10 that I can download to the 40 (45) but if I want more then that have fun with the 40... There's also something called a reload, it takes no longer or less time than drawing to first shot...then did you lose count or shoot to slidelock because you hold so many rounds? Criminals on average pretty much suck and your average ccw is slow because they practice on a static range, the old 45-70 is still a great round because it's a big thump. Something smaller and fast just just says ouch for enough time to get more thrown at you. This an old proven story by present day facts. Sorry for the rant, trying to wind down to go to bed.

I firmly believe in the "big heavy bullet slower speed methodology". We aren't shooting 200+ yards with .45 so the trajectory isn't a huge consideration in 50yds and less range.

There's no replacement for displacement as they say in the car world...

Well, if you bend the extractor INWARD, the lack of inner pad allows it to get deeply toward the bore, hence 9mm case. When the case is under the hook, the pressure OUTWARD has to torque against the outer-pad spacer/fulcrum - rather than transmitting the leverage further back along the extractor.

I'm just spitballin' here, but that would be my take on the mechanics.

The extractor is already under tension with no case present, since its hook has to be forced aside to remove it.

If the outer central pad was supposed to come into play when the case was under the hook, wouldn't that make the central pad critical? We don't see any mention of any fitting for the outer central pad.

I'm spitballing myself, but it seems the outer central pad should either be always in contact, or never in contact.

A properly fitted 1911 9mm extractor should still work fine without alteration. It does require the right amount of tension to work properly. I always use slide stops that are longer at the inward part in the frame, so the gun will go to slide lock after the last round is fired, or I weld them up to work properly. Years ago, before I started building my own guns, I would find 1911 ,38 super or 9mm guns that had .45acp slide stops, and the slide would not lock back after the last round was fired. There is a difference in a 9mm slide stop vs. a .45acp slide stop......

Ok, but then the outer central pad will no longer be in contact with the extractor tunnel wall. So now it's back to the original question, why is the outer central pad still there?

You would also bend it for more/less tension with the middle pad as the fulcrum point. Done that way with the bend at or forward of the pad, the spring tension would be from the middle pad, keeping the pad in contact with the tunnel wall.

Is this a test that you know the answer to? :)

Ok, and now we are back to the second question again:

Why is the inner central pad removed?

No, not a test

The questions came up for me while fitting a 9mm extractor.
