+P yes and since M&Ps have a fully supported chamber you will be okay with +P+ sparingly.
Great, thanks. Do you know what S&W recommends?

I don't know exactly what they would say, but someone else on here might know.
OK. Thanks for the replies...
As far as I know all M&P pistols come with the same manual, as the manual does not have a caliber designation on it. The manual that came with my .357 Sig says:
"Plus-P" (+P) ammunition generates pressures in excess of the pressures associated with standard ammunition. Such pressures may affect the wear characteristics or exceed the margin of safety. Use of "Plus-P" ammunition may result in the need for more frequent service.
"Plus-P-Plus" (+P+) ammunition must not be used in Smith & Wesson firearms. This marking on the ammunition designates that it exceeds established industry standards, but the designation does not represent defined pressure limits and therefore such ammunition may vary significantly as to the pressures generated and could be DANGEROUS.
Most manufacturers' manuals always say to never ever use even +P. Given that their lawyers did not force them to say that, I would say any M&P will be fine with +P loads.

My friend owns an M&P45 and he wanted to use Buffalo Bore ammo so he called up S&W and they said it would be okay but not a steady diet of that ammo.

Right. But as I don't own this weapon, I don't have a manual to reference. I take issue with a weapon that is designated Military and Police but is incapable of handling NATO spec ammo. Most weapons on the US market are not able to stand up to the use of this ammo as is it much hotter than US ammo. It is a shame, as I believe that the 9x19 would not be so maligned here if guns and ammo were built to the correct specs. I am trying to accomplish some research before making a purchase, but thanks for your insightful response!
