There will be lots of news stories about criminals (who don't have a permit) who were caught with a concealed weapon (to imply that having a concealed weapon permit will turn one into a criminal).
A "high capacity" magazine does not mean a whole lot. The current ban limits magazines to 10 rounds. One could carry a loaded gun and easily carry two or three spare magazines. The prohibitionists' goal is to eventually limit magazines to one or two rounds, which would make semi-autos impractical.
Wonderful hysteria about "easily concealable assault weapons with 100-round magazines!" A handgun magazine of 50 rounds is bound to misfeed a lot. There is nothing magical about a bulky Tec-9 with a 50-round magazine. That would be a jam-a-matic! It might hurt you if someone threw one at you. Anyone with a quality revolver or semi-auto is better armed. I wouldn't trade my Sig 220 for a room full of Tec-9s. A really good and inexpensive high-capacity handgun is the CZ-75, but that is just my preference. One should be able to find 15-round magazines for it and they won't jam.
All I want is a weapon that works when I need it, and a government that stays out of my way.
