: I think the most practical solution would be similar to the first idea
: posted: the shotgun is merely a lever-cocked breechloader. Pulling
: BACKWARDS on the lever would break the breech and eject the spent shells.
: The Marine probably has some sort of spring loaded belt clip (or any other
: shell dispenser), and as he moves the gun downward, slides the breech over
: the shells and chambers a new round. As the gun comes back around, the
: lever is pulled, closing the breech and cocking the gun. Rinse bad guys
: with buckshot and repeat.
Or maybe he whips them out his sleeve like the master cheif in halo 1 lol. (Well it looks like he's doing that).
