You definitely have a point there. Getting rid of all the magazines would be most likely, an impossible task.
Unfortunately. I am all for common sense gun laws (and there are many things we can do). But it has to:
1. Work
2. Affect the people committing the crimes (who are by far the ones committing the crimes)
Simply making things illegal doesn't do anything. Murder is already illegal. Someone intent on committing murder isn't going to be stopped by a law.
