Dwight,
Regulations, or rather working around them. If a barrel has a fire proof on it, it doesn't have to be proofed again
Tom,
I'd expect capture marks on all impounded/captured/marked equipment to be equal. Don't think anyone bothered to make a separate mark for captured K98s, P38's, P08's, etc...
But then again....Logic isn't always part of the equasion...
