mcole.
I replaced the extractor in my CD FS a few months ago. I just ordered a regular 1911 extractor from brownells and it fit just fine.
As far as I know the only parts that are not standard are the grip screws.
I just used Brownells because some friends said they had good prices and recommended them. I think the extractor cost around 12 or 13 dollars.
