The “Luty” is a submachinegun designed by a British feller specifically as a form of protest… a protest against British anti-gun laws. The goal was to show that an average person with minimal skills and access to s basic workshop and some off the shelf hardware could make a functional 9mm submachinegun. I’ve seen a lot of people talk about this gun, but few actually go to the bother of building it. And it turns out that following the directions does result in a functional firearm, though not a particularly *good* one. It might be interesting to sic a decent gunsmith onto it, and modify the design to make it a better weapon. Better trigger, better magazine retention and basic rifled barrel.
As it is, it’s a poor firearm. But a poor firearm is better than no firearm in a situation where the badguys – criminals and/or oppressive government agents – are better armed than the citizenry. As with the old “Liberator” pistol, a Luty can be used as a way to shop for better guns.
