I have always heard that the primary function of the extractor on a Luger is to grab the rim of the case, and hold it against the breechblock face until the ejector forciblby removes it.

I have noted over the years some things about the extractor and its spring in problematic pistols. I think the more common might be the spring is too short or too weak, to allow the holding of the case in place. Take an empty case, insert it into the loose breechblock train, it should kinda snap into place, with a feeling of tension holding the case in place. If the case is loose or falls out, this will usually cause an unintended movement early in the fired circle, usually falls into the works and jams up. I believe that the ejector likes some resistance to its upcoming force to the fired case.

Likewise I have seen broken extractors, when a new extractor is fitted, it is found that the compression of the spring in its cavity by the extractor going over the case rim, does not allow for some tolerance to allow said exactor to move over the rim without extractor springing. some people poo-poo that check, but with today's parts, might wanna check that capability of movement. Tis not a 1900.

Finally the ejector, a marvelous piece of steel it is. Broken nose, ill fitted in the cavity(loose) will not give the leverage needed to kick the case away from the breechblock face in the intended fashion

A few years back Huntingtons(RCBS) had extractor molds for casting parts. Never knew all of the ins/outs of the fab of the smaller parts, just a clue perhaps.
