A extractor depressor plunger pushes against the extractor which forces it to rotate toward the breechface. This rotation applies pressure against the case thus holding the empty case during the extraction process until it strikes the ejector. The spring loaded bearing, extractor depressor plunger and extractor depressor plunger spring stack up to push against the slide cover plate on one end and the extractor on the other. Any change in the length of this, the assembly will affect extractor tension.

Note: NDZ always recommends any part be installed by a qualified and trained gunsmith. NDZ promotes the use of safety practices and gear when working on any firearm.
