I own a Gun Range in SW Texas and own three S&W M&P 9s. A new shooter just brought in a new M&P 9 M2. With reloads that had no problem in any of my M&Ps, hers refused to go into battery twice. I brought her ammo into the shop and chamber gaged it and all passed easily. She will be back tomorrow and I'm to to inspect the chamber for tool marks, etc. and the remainder of her ammo.
