Hindering reloading would not have been a factor in Newtown. It could very well be a factor in defending your house from a home invasion with multiple assailants.

There are ways of making it harder to make your own clip if you want to. Just ask inkjet printer manufacturers about it. Seems a bit overblown and too much work for the trouble though.

The history of of gun regulation is that if given a choice between annoying as few current gun owners as possible and maximizing the number of dangerous weapons taken out of circulation, governments always choose the first.

So yes, a government that actually wanted to ban as many magazines as possible holding more than ten rounds would not try to confiscate all of them. Instead it would make the process as painless as it could.

I disagree. I see significant evidence that the 1994 AWB was associated with a decrease in gunshot deaths when in force, and an increase in gunshot wounds when it lapsed.

Gunshot deaths failed to increase only because because emergency rooms got better at treating gunshot victims.
