I must admit that I am a little concerned since NY passed a bill to restrict owners of weapons to 7 rounds. The governor of Ct. was heard on tv tonight saying that 10 or 7 rounds was good for him. Other than the Colt 1911's, how many factory mags are available for 7 rounds. I don't see any made for the SW MP series. How many manufacturers will produce mags of differing sizes if different states make their own rules? Why can't this be challenged by the NRA? At least have everyone stick to the 10 round federal size if it comes to that.
