If they ever come for the guns, give them the guns bullets first.
1 take away high-capacity magazines
2 take away semi automatics. (Which is even revolvers under their definition)
3 take away higher powered guns and ammunition.
4 tax guns annually and ammunition as you buy it at an exorbitant rate.
This is all done one step at a time. The notion that the government is going to come to your door, before these steps are done, is crazy. It is like everything else one small step at a time
By this point you have gotten rid of the majority of the people that own guns and the only ones that still have them are the small minority of holdouts. That small minority will be easily overtaken by the military. Even as Joe has said what defense do you have against A F15.
