Getting way off the subject (traveller) but I believe that the slide
breakage problem the US Army experienced was a result of using submachinegun
ammo (black stripe on case around primer?) in the 92F pistol. However,
it is interesting that traveller allows substution of ammunition between
submachineguns and automatic pistols (If I remember correctly). Then
again, with that many worlds, tech levels and gun-makers, a character in
a super-accurate campaign would be nuts to trust ammo bought on a different
world than the weapon.
