Personally, I think it would be better to carry an semi-automatic with more capacity. The M&P Shield will carry 8-9 rounds and the M&P 2.0 Compact will carry 16 rounds. And then I'd get good and comfortable with it, learning to shoot it as accurately as I can. I don't know of any reason it couldn't be as accurate as a revolver. If you're set in your ways, stick with the revolver--it'll do fine.
