It's just different than any I have ever seen on a 1-2-3rd Gen pistol. I've seen plenty of pistols with an extractor of that style, but never one of these pistols. Appears to be a very short extractor with a spring behind it and pushing forward -- rather than a spring under it and pushing outward.

Don't yell at me for saying but it reminds me of a Glock extractor and/or the one on my Star Model 30 Starfire.
