I picked up one of those as soon as my dealer could get them. I'm rather fond of mine. The email I got from S&W was that the guns are +P rated, but nobody else seems to agree. It doesn't matter to me. I'm going to use standard pressure for practice and +P for carry with just enough +P fired to check POI. Recoil and POI is generally pretty close between standard and +P for standard pressure practice to not be a factor.
The only thing I don't like about mine is that POI with 158gr loads (+P or not) is 5-6" high at 10yds. Standard pressure 110s are dead on to a hair low at 10yds. I'm hoping (fingers crossed) that some of the current middleweight +P loads (125 and 135gr) are within an inch of POA. Windage is dead on.
