Anecdotally I had heard that there was only one fully transferable 1911 machine gun. It was made and registered before May of '86, but it didn't work. At some point someone bought it, and had someone who knew what they were doing rework the mechanism in a way that functions. If that anecdotal report was accurate that video may be the one and only one of its kind.
Full auto Glocks are plentiful, but there are zero fully transferable ones. None were made and registered prior to May of 1986 so the are all "post-samples".
