The Germans are the machine tool masters of the world, they need German patriots to start producing underground firearms to re-arm the German people. Even black powder style single actions are better than nothing. They can use pyrotechnics for powder, firecrackers for primer, and lead weights for projectiles.
Perhaps American patriots can airdrop WW 2 style ‘liberator’ pistols like the ones the allies dropped to resistance groups during that war. Funny how we are at war with Islam but none (or next to none) western leaders are aware of it.
What about stun guns?
