I bought the original .357mag scandium/titanium 360sc quite a few years ago. That gun is no longer produced, but the currently-produced 360PD is essentially the same, except for cosmetics. For some crazy reason, S&W has since used the 360 number to refer to several very different guns ... sometimes with a steel cylinder instead of titanium, and sometimes only shooting .38+P (not .357mag). Seems like a dumb thing to have done.
