One of the strangest pistols I ever encountered was the Radom VIS 35 that my father brought home from WWII.

It was a single action automatic, with a decocker and a grip safety. No manual safety like a 1911 or High Power. If you carried it with the hammer cocked, the grip safety was all you had. If you carried it with the hammer down, you had to manually cock it and the hammer did not have a big spur on it.

I wouldn't have wanted to carry it, but being all steel and 9mm, it was practically recoil-free and very accurate considering the crude sights.
