IIRC, the magazine ban is three fold.
1)Magazines may not be loaded over 7 rounds, effective immediately.
2)Magazines over 10 round capacity must be sold out of state or disposed of within one year.
3)Magazines between 7 and 10 rounds can be brought into the state until April 2013 and can be kept/used after that date but no more may be brought in and they must be loaded to 7 rounds only.
Yeah, because criminals intent on shooting a room full of people will be careful not to be charged with loading too many rounds in a magazine.
