Mafia Graves Visual Tweak (Red Post Pease)

Is there any plans on updating Grave's weapon into a shotgun from the same time era as his current weapon? He's clearly wielding an automatic weapon, if I'm not mistaken the the Tommy. Wouldn't it be more cohesive to update it into a shotty of some sort? Just for asthetics, you can also update the SFX into something very nice from the same era.
