Before this discussion becomes idiotic, the mag bill is useless and the one I am disappointed about. The background check bill makes sense and I support it. To the idiot that said this covers the majority of firearm sales in Colorado...ah no. Two other bills were defeated. One banning firearms on college campuses and another that would charge a firearm owner if a crime was committed with a stolen firearm.
However if you already own mags that hold more that 15 rounds you are grandfathered in. Second, the way the bill is worded will most likely be challeged in court.
I've had several family members killed in mass shootings and gun violence and none of these bills would have saved their lives.
