no4 mk1

[sig shooter]

i have aquired a nice no4 mk1. the only ammo that will seem to chamber in the gun is small rimmed surplus, the extractor will not fit the thick rimmed comerical 303. is this a problem with the extrator or is how all no4's are?

thanks

I'd say its your extractor.

Yeah, I've shot about 4 different brands of commercial and several military surplus types, and never had a problem - something is not right.
