Check the AO-Hell Journal entry. He talks about how and why it happened (to him) and has a few photos regarding the fix.
This guy does too, roughly half-way down the page. Typos and spelling errors galore, though.
url=http://www.mit.edu/~boojum/Oath/PC/Jim/Papers/smallarms.html]Problem #3[/url] he states the bushing shattering on his Combat Commander and sending his recoil spring and plug downrange. Also mentioned is the Officer's Model, as well as fixes for it.
From everything I've read, the sole way to fix this problem is to install a reverse plug. Unfortunately, it also requires a trip to a gunsmith or a lathe to cut a ring in the slide's dustcover. I haven't found anything regarding a way to reinforce the lock tab on the recoil spring plug. You might want to try asking on 1911 forums.
