Well most of the state and city bans to limit the 2nd amendment were struck down by the courts.
So the left has been pushing 'back-door' laws that would do the same thing, effectively: huge taxes on ammo, letting manufactures be legally liable crimes committed with their sold weapons, etc.
Regardless of your views on guns, it is the 2nd Amendment - if the left wants to change it, there is a method to change the Constitution. Executive decisions and other nefarious schemas shouldn't be accepted.
