Just for grins, put the slide on the frame without the barrel and spring and see if you have any sticky spots from the finish. Mine did and gave me no end of woe until I got that sorted. Which consisted of working it back and forth with no lube for a few minutes. Perfect since.

I do see that the extractor is too long. Those who know 1911s a thousand better than I do (which wouldn't take much) say that long extractors are common on production pistols.
