Hi Skunk,
I'm the wrong guy to ask what other guns have external extractors besides the KZ45, but from what I understand, one of the (very) few flaws of JMB's original 1911 design was that the extractor relied on a single piece of spring steel (the extractor itself) to maintain correct tension.
In other words, when you fire your 1911, you're flexing the extractor. After a while, they wear out, or change tension, resulting in FTE's.
An external extractor can be made of a very rigid piece of metal, and tensioned by a calibrated (and replaceable) spring. It can also be hinged, since its travel isn't limited by the extractor slot. You end up getting a more reliable extractor that way.
What I don't know is, now they make 2 & 3-piece extractors for 1911's with springs inside them, extractors that have funky shaped shanks, etc. Do these help? Anyone? Bueller? Bueller?
