In 1964 there were far fewer regulations of firearms, both civilian and military. When facing movement to Vietnam I shopped at the PX in the Philippines thinking of buying a S&W .357 to take with me. Never got around to it.

In Desert Storm my Army Reserve aviation unit was still issued M10's. Of course, by 1990 all firearms were tightly regulated and no personal weapons were allowed without written authority of an O-6, or higher. Consequently I caught a lot of grief because of my M10. Everyone thought I was in violation of the general order.

I dared on REMF O-3 to confiscate my weapon, but he backed down.
