The Voevodin pistol was an experimental Soviet semi-automatic handgun developed by a certain Soviet designer P. V. Voevodin in the late 30s as part of a competition to replace the TT-33 service pistol. It was chambered in 7.62×25 mm Tokarev and one of the cool quirky design was to not have a reciprocrating or tilting barrel so that one can fire from the slit of the tank, for you know, tank defense. Pre-WW2 was a wild time.
Not much information is known on its actual operating features but it might be similar to the Lahti but without a lot of its short recoil principle, etc.
Takes pistol stock and muzzle devices.
Thanks Boggy for the help!
