bereta1, did you ever get an answer? Dennis sold me an extractor that he called SGW "Raptor's Claw". Tandemkross lists an "Eagle's Talon" extractor, but they are out of stock. Volquartsen lists one they call "Exact Edge" [VC10EE] that appears to be available. I don't know who his supplier was, but I'm pretty sure it was one of these two.
I, too, am sorry to hear of Dennis passing. He was very helpful to me. Prayers to his family.
Could be, I don't know. In another forum he said there are six aftermarket makers of the extractor, that he had tested all of them in a number of weapons, and that he had come to use only the one version that he found to "work perfectly".
He also said he used a lot of Volquartsen custom parts. Perhaps I drew an improper conclusion
