Indeed, that is a fun fact!
I'm pretty sure I heard that somewhere before, though. I'm not surprised that the North Vietnamese had their Thompsons rechambered for the 7.62mm Tokarev round, they had a ton of that stuff!
Hehehe, thus proving my point about how assault rifles made submachine guns obsolete!
With an AK47, you get the power and range of an SKS, and the volume of fire of PPsh-41, all in one glorious, durable package.
Thank you for all the advice you gave me prior to drawing this.
I mentioned in the text that I plan on continuing with submachine guns; I'm going to include the Carl Gustav M45, the Smith & Wesson M76, the Colt Commando, the PPs-43, and the modified MAT-49.
