would you have been able to buy 357 mag ammo at the PX? either that or have the foresight to take several boxes of ammo with you on the way over. maybe relatives could have sent also?
The impression I have is that in the 40's and 50's the U.S. mail was a little more loose about things like guns and ammo. Many a soldier recieved a handgun in the mail back then. I would imagine it was the same for ammo.
