Tony;
I may have been barking up the wrong tree, is this a hammer gun or hammerless. Don't know why but was thinking hammerless. If a hammer with them in the rebound position with bbls off see if the pins push back freely, flush with the breech face. I can't really say that it is universal, but the vast majority of hammer guns do seem to have retractor springs on the pins. I suspect this is because they often have a downward slope toward the points. Another question, did you perhaps misplace the decimal point & mean .200-.300 extra protrusion. That would for sure indicate a missing spring.
