Not that I think its gonna happen (again).... But all current hi cap magazines are grandfathered in so you will still be able to use them. Hense why every one is loosing their mind and buying them up. This was what fired up the resurgent of the 1911 45acp back then. A better idea is Stay Strong and fight the very idea of a ban. Let others know you enjoy shooting and own many guns and are proud of it. Don't let the media push or shame the idea that only weird people own guns. They are trying to change public perception like they did with smoking. Don't let it happen. The government works for you and not the other way around.
"I'm a good guy with a gun" What do I care if I give up some freedom or rights?....The Goverment will take care of me. This kind of thinking is now in the majority and it should concern you.
