I have a 2.25 and 3 Inch both chambered for the 357 Magnum, and I do carry the 357 Mag 135 short barrel loads in them.
My brother has the sweetest SP101 38 Special I have ever had my hands on. Tuned to perfection. Gemini Little Wonder fiber optic front sight. Fancy Lette fish scale grips by Altamont. He is perfectly happy with it shooting 38 +P carry loads. I doubt he would carry 357 Magnums in it, if it would shoot them.
