No.
Back in the day, S&W customer service would tell you the Model 36 was not +P rated, and would eventually shake the gun loose sooner then standard pressure ammo. But that there was no safety problem with shooting it.
But +P was loaded hotter then then it is now.
If you plan to shoot it a lot at the range, I'd go with standard pressure ammo and practice just enough with +P to know what to expect when you carry it for serious use.
+P won't be as much fun to shoot in mass quantities anyway due to the increased recoil.
