Alright. I guess I won't be using Daddy Liberty- unless he gets a hold of an M1 Garand with a five round magazine, which could be fun on its own.

You could use any weapon with the round limitation, it's not that difficult for your character to just be given magazines for their weapon when they arrive with the lower capacity.
