Swiss Armco PM 1950 submachine gun

man, cooling fins on barrels look so cool (even if they're of dubious utility on a submachine gun of all things)

although nothing can match Japanese WW2 machine guns, some of those are practically constructed entirely out of fins

I want the barrels of those guns to flop around like a door stopper spring and make the same noise when they are fired.
