According to the information on the Four Seasons web site, Springfield has no intention of trying to get any of their hand guns certified for sale in MA.
It holds 10 rounds with it's magazine. It can actually take a full size 16 round magazine, and it has a sleeve that fits such magazines so the grip is perfectly extended. Unfortunately, such a magazine would not be legal for me. I could always get a full size 10 round mag and put a sleeve on it, thereby giving me a full grip, but its only a 9mm, so the kick is small and I figure I don't really need it.
