The Spasov M1944 Trigun was a triple-barreled submachine gun of Bulgarian origin, and a rare variation of the Spasov submachine gun. It was chambered in the 9×19mm round and had a very high rate of fire, at 1500 to 3000 rounds per minute, if you think cönders was a monster, this beauty for event or battlepass could be even more funnier, what do you think guys?
Very little is known about Hristo Nikolov Spassov and his guns. (none of his guns progressed further than prototype stage nor seen combat) The most information is available on the Spassov M1936/1938, which he had designed for Bulgaria on his own coin out of patriotism, but after his machine gun design was rejected by the Bulgarian army, he had sent the design to the Soviet Union.
(There are two surviving M1936/1938 today, one in the Artillery Museum in the city of Saint Petersburg and the other in National Museum of Military History, Bulgaria)
It would be logical to give all of his guns to one faction.
Also, this is a late war design, if it had seen combat (which it did not) it would have been against the Germans and Hungarians.
So the final verdict should be the Soviet faction.
