A lot of the parts are...depends in some cases how the guy that drilled the pin holes felt when he did it. I know the extractor is, or was, cause when I had my Hardballer period, I had to replace the stock (Cast!!) extractor after about 30 rounds on a new gun. Used a USGI part and solved the problem. On the other hand, had problems trying to install trigger/sear parts to correct a horrible pull because the pin geometry was off-gave up in disgust. About the best advice I can offer is try it and see. Aside from the trigger itself, all the parts are supposed to be 1911 specs.
Thanks mine is in pretty good condition. It has a pretty smooth pull. I was told elsewhere on this forum that it is an original gun made in the 1970's. I like it personally but have not fired it more than 100 rounds so far. We will see how it does.
