Are M&P's built to handle +P ammo? What about +P+?
Check your owner's manual, but in general, for +P, yes.
Reality- there is no standard definition of +P+, so no maker will rate a gun for that.
There are OFFICIALLY only 4 +P loads- .38 Special, 9mm Parabellum, .45 ACP, and ALL .38 Super ammo. So says SAAMI. There may be other calibers that are CALLED that, but SAAMI (body that sets ammo standards) does not HAVE a standard except those 4.
And +P is really not all THAT hot. A .38 Special +P is still way below a .357 Mag.
