I believe the gun that Greg Hartman tricked out for clay shooting had a "popped rib."

The year I went to the U.P. shoot I saw another one.

Andy's Custom shop mentions loose ribs first in their discussion of common problems with 21s

So there is probably at least something to the notion.

Or it could be that many other guns have just as many problems?

FWIW
