I've lightly lubed the extractor (where it's shiney from rubbing) since the 80's. Anything that is shiny from wear needs a thin layer as rust prevention IMO. Old School training. A thin layer of modern ester lubricant will leave a protective film when dry and there will be no accumulation of carbon beyond normal as well as making cleaning easier. Not that the force exerted by a spent cartridge does not have enough force to overcome the extractor spring's resistance, but lubricant surely aids the process as in any other mechanical area where metals meet via friction.
