The goal is to make the grenade launcher more viable by letting traitors hold multiple grenades. Maybe make it so they only get the grenade pouch after buying the grenade launcher. Ideally the traitors would be able to hold different types of grenades, but I'd understand if that would be too time consuming to implement. Additionally, consider making the grenade launcher a slot 4 weapon (unless it is already, honestly I'm blanking on this at the moment).
