We're up the same issue here in Maryland. The current State Law only allows the purchase or transfer of magazines 20 rounds or less within the state. When the new ban kicks in on October 1st, the new limit will be ten rounds. Since only the SALE or TRANSFER is banned, not possession, everyone just drives across the state lines to PA, VA, or DE and buys what ever they want.
The only real demonstrative effect the law has had is to really pi$$ off and polarize gun owners against the current Democratic administration.
