Limiting magazine capacity is a really dumb idea. Being a former resident of California (who went to limiting mag capacity to 10 rounds) I have seen how in-effective it has been. What is to keep criminal elements from purchasing high cap mags? Nothing. Pre-ban mags can been purchased very easily or people just purchase kits and build their own. Heck, I have a few friends that are mechanical engineers that have access to CNC Machines. They would have no problem building me a high cap mag if I asked. Gangs typically just have their buddies ship hi cap mags from other states in which they are legal (problem solved for the bad guys). Once again, only the lawful firearm owner gets screwed when limiting magazine capacity...
