I've heard that urban myth too. Over the last 3 or 4 decades, I've owned 5 Colt Series 70's w/collet bushings (still have 2) and fitted a 6th bushing to a generic M1911. Never had any problems whatsoever. It's never anyone with firsthand experience writing about it; it's always "my wife's brother's best friend's gardener's cousin's son-in-law's drill sergeant's father" whose bushing broke.
I've never seen any recall notice in any NRA publications or gun magazines, or any announcement from Colt. To my knowledge there has never been any magazine article about the bushings breaking. I would suspect the change back to solid bushing was a cost saving measure.
I would further guess that the Teflon bushing was dropped for the same reason. Too little demand for a more expensive bushing.
On the reamer - They are actually pretty cheap, even for a use-once. I've added one to my next tool purchase list.
(It's the 17/32" to 19/32" size)
