Need some help with weapon systems

Here is the problem: Not sure if the details were explained clearly but there it is. I cant t$$anonymous$$nk of a good way to implement what I have in mind, all I can t$$anonymous$$nk of is bad ideas, like making bunch of prefabs to make it.

Here is a slightly better way I can t$$anonymous$$nk of: Here, I plan to make the weapons into a class, then have a monobehaviour script initialize them (not sure where else I must do it). Then I'll make 2 list, Armory1 and Armory2 then assign function to add Weapon there that will be called. Then I can simply get the summation of the damage of weapon in list by iterating them in a for-loop

That's all it is, I t$$anonymous$$nk. I hope to know more about implementations of classes and lists. Any help will be greatly appreciated. Thanks!
