I have too much time on my hands. Cruising Rugers websight, I see identical SP101s, chambered in .357 and .38 Special. Since you can shoot .38s from a .357, why is there still a dedicated .38? Its not a service revolver, so the idea that some official use commands .38s only doesnt make sense. The .38 model isnt a lightweight aluminum revolver, like a S&W 638, and isnt a few ounces lighter, like the difference between the .38 and .357 LCR. So what do you think the reason is that Ruger keeps it as an available model?
