Just got one for my wife and she wont shoot. Anyway I went to trade it in and to low of offer so Ill keep it for now. Problem was the mag dropped on its own and I sent it in to s&w got it back and it sometimes will still drop. I guy said it might be my thumb hitting the release I have big hands and Its hard to tell for sure. I put a mag extender on before I sent it in. Does anyone have a idea about how to extend it any more. They don't offer anything longer for the ez. m&p they do but wont fit the ez.
