I think a better way is for the States (like mine is doing in Missouri) to create 2nd Amendment sanctuaries, nullifying the Nazi gun control laws. Some of our counties are even going as far as putting into their laws the ability to arrest Federal officers.

Some will say that Federal supersedes State... well, we are a Republic where States rights are paramount.

Besides there is precedent for this -

Example 1: Feds still have Marijuana on the prohibition list. Yet 1/3 of the states have legalized it.

Example 2: Fed allowed without action certain cities and states to declare themselves sanctuaries for the illegals.

Either way, these Nazi gun control laws will be challenged in courts.
