Dunno about guns, but if you google image "pirate guns" you'll come across a bunch of surprisingly similar looking models. There's also a possibility that the animators just drew whatever and didn't really model the gun after a certain existing one.

Also, our admins are probably gonna have to delete your images because we have intense image guidelines @@ but don't mind us.

Good luck finding it~
