A gratuitous photo since I have nothing better.
Note that the moon clips are already loaded on the vinyl versions.
Another note: although the revolver is a six-shooter, back during the war the ammo for this gun was issued with the clips already loaded with 5 rounds per moon clip, so apparently the gov't intended for this gun to be carried with an empty under the hammer for "safety." Which probably meant there were some people pulling out .45 rounds and filling all six segments anyway. If I was in a combat zone, that's what I would have done.
