Shotguns
Lever-action Shotgun, 20GA (ST 4, resembles Winchester model 1887)
[i]Riot Shotgun
these 2 are one of the reasons I <3 Vegas already.
I notice in a demo showing the icon for the level action shows the stock being cut down, not impossible it′s aimed at resembling the level-action from Terminator 2 (possible including the trademark one hand spin cocking motion from the same movie).
I also read there is a theory that the riot shotgun might be pump action :3
