Hard to tell from the pic exactly what ridge your talking about but I will say that there can be a lot of tooling or casting marks on the trigger bars of these guns on that lobe area that the red arrow is pointing to. and there's usually some scratch looking lines on the side and that's normal with the function of the M&P trigger system. There's kind of a sharp milled section of the slide that "bumps" into it when the slide cycles back and that's what resets the trigger. After the gun has cycled several times, its usually as bad as it gets. after that, the part is essentially worn in to that gun. I polish the hell out of that nub of the trigger bar to deburr and smooth out any tool or casting marks because that's what contacts the striker block and can cause some grit in the trigger pull.
Hopefully all that helped!!
