Anyone know if 30 round magazines are generally legal in the US? I think they are because they said the Connecticut guy legally had one and I would think Conn. would be on the liberal side of the gun issue. It is kind of amazing that more of our liberties with guns haven't already been taken away. 30 rounds is pretty wild. I own a gun and have shot many other people's guns and never seen anyone break out a 30 round clip.
