I actually have a somewhat rare Browning 9mm, in firing condition, that my father brought home from Nazi Germany.
I had one, once upon a time. Some fool had fired a very hot round in it, and bulged the barrel, so I reluctantly traded it off for something else, and I don't even remember what. Should have just bought it a new barrel for shooting, and kept the matched serial numbered one for whatever collector's value it might have had. Perfect hindsight, as usual.
