Well on that note, is there a big difference between the internal and external extractor?
In my opinion its just another 1911 purist argument. The only real arguable advantage I could see is its safer to drop the slide on a round in the camber with an external. Doing so with an internal could cause damage much faster. Some failed to implement external extractors well, kimbers early attempts IMO. I have never seen any issues with externals from Sig , s&w or para.
