Kel-Tec SUB 2000s: The company lost contact with the private buyer that ordered them, so they donated the weapons to the Ukrainian government.
Hope they told the recipients not to use +P ammo in them.
Only issue with these, as stated, is that the SUB2K can't take military-grade +P ammo. The folding makes it too fragile. But it would be good for my fave Ukrainian cat lover: Cats, Guns, and National Security: THE DAILY FUDD: E181: "Fantasy fudd: Ukraine -- The way it ought to be."
