Scotland Bill

I am genuinely trying to understand this. If the Scottish Parliament was to have power to regulate those ““less dangerous”” air weapons, how would it do that without having a licensing scheme? If my noble and learned friend’s argument is that they are required to be part of a licensing scheme, I do not understand the logic of it. If the Government’s view is that the Scottish Parliament ought to have this responsibility, is the Minister saying that it can only have responsibility for weapons if they are not very dangerous? It seems to be a little illogical to me.
