fingered bushing for 1911

That is the Colt Mk IV Series 70 Accurizor bushing, originally made for use on a slightly flared muzzle so it will lock up tight as the slide closes. If you have it on a plain straight barrel, it is dependent on the spring of the fingers to center up.
They haven't been made since the early 1980s, but you ought to be able to find a takeoff in any gunsmith's reject bin because people are afraid of the fingers breaking off and jamming the gun. So many of them have been taken off and replaced with standard bushings.
I don't see how breakage would be a problem on a straight tube, but then I don't know anybody who has shot one that way a lot.

I have heard that of the posiblity thay could brake but I had it in a colt combat eleat that I shot in combat shooting in the 80s and put 5000 rounds thrue it easy . and now it is in a pt1911 that I got when thay first came out and have shot at least 1000 rounds in it , and the accuresy is excelent. My brother enlow has checked it with magnafux and a spay on crack ck. and it past both. I would love to find about 6 of them for other 1911s I have . I was told when I got it that it came out of a 70 seres gold cup but was not shure as the 2 I have do not have that bushing . thanks for the info .

Bad idea.
I have repaired two guns in the last few years that had collet fingers break, jam inside the slide, and lock up the gun to the point it could not be taken a part without drilling the slide stop pin out.
Or beating the slide off and scaring the barrel and inside of the slide.
It was a short lived "improvement" that Colt probably still wishes they hadn't done.
If you must use them, buy Kuhnausen's book "The Colt .45 Automatic, a Shop Manual".
In it he goes into great detail on how to properly fit them to prevent breakage.
But I'm here to tell you, you are much better off in the long run to use fitted solid match bushings fitted to your barrel.
They never break and damage the gun.

If you must have them you can find them on e-bay.

Barrel bushings
RC got it right, use the fitted bushing, it only takes one failure to really mess things up. Al

And in addition, they won't work on a straight barrel. They must be matched to a Colt Series 70 barrel, or one made to the same dimensions.
And rcmodel is right. If a finger cracks you will have MAJOR problems getting the pistol disassembled. If the bushing goes south when you're in some sort of serious situation you may not still be around, if or when the pistol gets fixed.
