There are some guns created by reactionaries which were actually used in based countries like for example DDR and SFRY used Walther P38 after WW2, and that's one of the cooler ones imo.
Yugoslavia repurposed MG42 into M53 which looks cool as fuck.
And imo Thompson is one of the raddest guns, and I'm actually used to it being a nazi exterminator along with PPSH-41 since I grew up with old WW2 movies.
Which are your favorites in this category?
There's also the "Kraut Space Magic" gun aka the G11.
The most overengineered gun perhaps ever in mass production. It literally picks up the bullet, rotates it, and then inserts it into the chamber to fire. And it uses caseless ammo for reasons far beyond human comprehension. It is magic because of how infrequently it jams.
It is also used by the UN troops sent by SEELE to invade Central Dogma in End of Evangelion.
YOOOO EVANGELION REFERENCE
