Assuming that the new M&P9 Shield is real, (I take "news" that comes from Reddit with a grain of salt...) then I have to admit that I'm surprised at how high capacity they made it. I mean, from a marketing standpoint it makes sense to 1-Up the competition, but considering all the rumblings of a forthcoming push for a reinstatement of an Assault Weapons Ban it seems rather bold. I mean, in the event of the passage of such legislation, the new Shield will have to be sold with 10 round magazines, thus rendering the overall size/dimensions of the pistol excessive, likely eliminating the only advantage it had over the competition.
Assuming that it is also available in .40 S&W, then it might still be okay, since it may hold 10 rounds by default, and the cartridge may get a resurgence in popularity in the event of a new AWB, but otherwise...Ouch.
