I traded for an M&P today, and didn't realize till I had already agreed to trade, that it had 10 rnd mags. I am now wondering if it is MA or California compliant. Is there any way to tell, short of calling the factory? The trigger feels a little heavier, but haven't felt enough M&P triggers to know the difference.Oh yea, anybody want to buy 10 rounders, or trade for 17 rounders?
