Well, if you go read the link I sent, the guys are speculating that it will take it fine since the newer Al frame revolvers are rated for the P+. Unfortunately none of them has tried it. If you don't practice with the hot rounds extensively it appears most people think it is fine. Of course the manufacturer will not recommend it due to liability (and marketing).
But back to my first argument, I don't think you need hotter than .38 special for self defense, unless you are planning on shooting through your door.
