Wheeler's post hits all the right explanatory points in the "you should carry .357 magnum in your small lightweight snubby" argument.
As one who quite a few years ago optimistically test-shot 20-100 rounds each of all then-available commercial premium .357 Magnum loads, with bullet weights of 110-158gr, in a pair of my S&W 340PDs (unrealistically hoping to find the ideal balance between "lightest weight" vs. "most powerful" pistol for CCW purposes), I would testify that first of all, shot-to-shot speed is unavoidably quite slow, and that precision is relatively poor compared to the best .38 Special loads (Gold Dot .38 Special 135gr+P JHP giving best results IME).
I believe that most folks who recommend carrying .357 Magnum loads in small "snubby" revolvers are essentially deceiving themselves, and that these little revolvers fill their particular niche best either in the role of backup guns carrying any number of top-quality .38 Special JHP loads, or, if carried as primary CCW guns, carrying either Remington .38 Special 158gr+P LSWCHP+P, Gold Dot 135gr+P 135gr JHP or perhaps full wadcutter 148-158gr loads.
