A gun should do the same damage as another gun given it’s setup the same.
A coachman with the same mods as another coachman should do the same damage.
But make it “Rarer” and suddenly it does more damage? How?
The receivers in Fo4, I could forgive for game-play purposes, maybe you could reload your brass with more powder or whatever, but the rarity system just doesn’t make sense, and honestly pisses me off.
Let’s say you have a real world “firearm” like the Mossberg Shockwave:

12 gauge, pump action, 5+1 capacity.
The action and machinery on it is the same as the full size 590, but the shorter barrel and birds head stock changes the performance on it.
On either of them, you make one small modification and now you can use “shorty” shells. So instead of 5+1 or 6+1, now you’re looking at 9+1, maybe more.

But those are still modifications. In SF, you can have identical weapons, and they will have different damage just because of some rarity thing.
Also, minishells are cool af. I just wish my semi-auto could cycle them.
The Mossberg uses a little rubber plug to take up the extra space, that’s the mod.

Oh I know, Ive seen it. Youre basically just short shucking it. But its still a mod.
