All that interests me is the ability of my '50's Model 10 to handle commonly available +P ammo for fun practice and serious SD.
Likewise my Model 15-3.
I suppose everyone must make their own decision. I am not trying to magnumize my K-frames...I have a Model 19 for that (of course, there are those here who don't feel the 19 will handle magnums either).
I will never buy enough +P to damage my Smiths. What I have fired did not seem that hot to me.
