Are these pistols something from a old Sci-Fi Movie?
No, these are the ultra-odd Bergmann Simplex Pocket Pistols.
Let Forgotten Weapons tell you all about these interesting Bergmann Simplex Pocket Pistols.
The Bergmann Simplex Pocket Pistol was a semi-automatic pistol that used a simple blow-back operation. With a magazine forward of the trigger guard, they were quite different than the modern semi-automatic pistols we are familiar with.
There were only about 4,000 of these little pistols ever made before they were done in, probably by the more popular Browning style pistols.
