Re: Cute, but not for long
Ask the French Resistanca about the "Liberator" pistol. Cranked out in large numbers from stamped parts, with the clips essentially built-in, then air-dropped over France. They didn't need to last long, just long enough to kill some members of the invading forces, then take *their* weapons.
Always an important part of defending your liberties is the ability to make things very difficult and painful for the enemy.
