The Liberator Pistol is a History lesson in itself,
if one is interested,,,
I've read about that little puppy. It was .45 ACP, had an effective range (due to inaccuracy) of about 7 yards -- funny, that's a typical gunfight engagement distance -- and one could copy them and turn them out in one's garage with just a couple of old, hidden-away machine tools.
They were air-dropped in numbers into occupied Europe.
Nasty little boogers, if you were a Nazi.
