Oh ok, I know exactly what you're talking about now. You could roll up emery cloth (or wet-use sandpaper) and use it to very lightly polish the bore in the bolt/extractor assembly, make it a little easier to remove. You wouldn't have to get real agressive or anything, just very light and even polishing to loosen the fit ever so slightly. We were referring to the firing pin retainer pin(#14), whereas you were speaking of the cam pin(#6) as shown in this diagram. Edit: Woops, posted late!
