I live in the Midwest and understand the challenge. The first step to passing an amendment is obviously creating the conceptual space for that to happen, and gee look where we are.
Go the Chris Rock route and charge an obscene tax on bullets for handguns. Also, make it illegal to own handguns.
Beyond some of the more obvious ones like our lawmakers know about (gun show loopholes, etc.), maybe something like requiring insurance, just like you have for your car.
There's a lot more regulation that can't be done but no willpower or even political power, seeing as that new terrible bill about concealed carry just got passed by the House.
