Yes, they are larger. Same as the glocks. The parts are scaled at about the same variances as the rounds... (I.e. the M&P 45 is as much larger than the M&P 40 as .45acp rounds are larger than .40...)
My advice is head down to your local gun shop. Try 'em in hand. With the M&P series, the adjustable backstraps can help fit your hand better whether large or small...
