I've never shot +P ammo in a semi auto. Seems like it would be pretty hard on the pistol. I wouldn't hesitate using it in a revolver.
Plus P is not really that harsh on the pistol. Presssure on the 9mm luger for example is held down by SAAMI because they have to keep it safe for the old pistols manufactured over 100 years ago. There is no reason whatsoever that a modern 9mm should not operate at the same pressure a modern .40 S&W operates at.
