Go talk to LEO's. Those AR's, Mini's, 870's, and pistols stay loaded almost forever, years and years. That doesn't present any issues to them. But tell the wife otherwise, 'but I have to go to the range, you know the magazines. What? No I can't unload them by hand, its not the same, metal fatigue and all that, it has to be the real thing.'
There's a horrible joke in there somewhere.
