Isn't the S&W M&P9 able to fire NATO, spec 9mm?? That stuff is +P+. Glocks, Beretta, Sig, all will handle NATO spec 9mm, I cannot imagine Smith building a pistol, calling it a Military & Police and not making it able to handle the +P+ loads that the military and many police departments shoot. If it will handle NATO spec, it will certainly safely handle +P.
