I have a older S&W M36 snubby as well...it has handled a very limited diet of +P ammo with no problems.
That said, with modern SD loads, it is not necessary to use +P. There are many standard pressure loads available these days that are plenty effective...such as the 158gr Buffalo Bore LSWCHP. Federal Nyclads are also great.
Bottom line is that you don't really need +P in in a snubby to be effective. As always, shot placement rules the day.

I think that one of the notions common to the anti-gunner is the idea that being a victim is 'noble'; as if it is better to be noble in your suffering than disruptive in your own defense.
