Doubs,
Without beating a dead horse unnecessarily, apparently we have a breakdown in terminology. The forward part of the toggle assembly is the breech bolt, and the front of the breehbolt is the breech face. On a Luger the breechface is partially recessed. The breechface must contact the cartridge in order to strip it from the magazine.
From your last post:
The rim and base of the cartridge do not contact the breechface while being fed into the chamber
During this stripping process the base of the cartridge rides up the breechface until it reaches the recessed area. As it rides up the breechface it begins to raise the extractor, and as the cartridge seats into the recessed area of the breechface, the extractor slips down over the rim of the cartridge.
I too agree, and thought that was what I said, that the extractor seats over the cartridge rim as the rim seats into the recess of the breechface. I have a feeling that the extractor functions exactly as designed. It will jump over a rim if a cartridge is dropped into the chamber rather than being fed from the magazine, but does not function and was not desighed to function that way during normal operation.
