This seems to imply guns would be more common but perhaps less diverse. One very solidly primary, most-common spawn, with at most the occasional acquisition of a pistol of a different caliber or an older-type shotgun.[/quote]
Primarily hunting rifles with either handguns or shotguns for home-defense, sure. One True Spawn seems a bit much–the government didn’t issue people weapons or subsidize one firearm over another (at least not any more than they do via defense contracting, etc).
Focusing on compatible ammo-types would make a lot of sense from the Civil Defense perspective: encourage civilians to stock up on .223 and 9mm weapons (and the manufacturers to ensure plenty of supply to meet demand), so if the worst-case happens the military can get ammo from civilian sources. Whether that’d actually happen is a completely different story.
(I think .223 and 5.56 NATO are intercompatible. But my experience is chiefly JA2 1.13–not a particularly reliable source. :-/ )if memory serves, a gun chambered in 5.56 can fire both, but if chambered for .223 can only fire .223 because 5.56 is a more powerful military round. [/quote]if i remember
