You should get used to it. I felt the same way at first, I went from 1911's to Glocks, to the M&P 2.0. It just took some getting used to, and I have since applied that sticky grip tape to my 1911's. I only carry the 2.0 now and I will never go back. It took some time, but after a few months the factory stippling has me gripping the pistol perfectly every time, sweaty or freezing. They did their homework, and they did it right, at least in my opinion.
As stated, you can take some light sandpaper and shave it down where it bothers you, but don't have someone "modify" it. It may not be what you want or like in the end.
