I just read that if you have the cylinder machined to accept moon clips on a S&W model 60 .357, you can shoot .38 Super, 9MM, .380 and several other derivatives of this type. I was tempted to have this done just for the convenience of having a quicker and easier reload in .38 and .357, but the opportunity to be able to use some of the auto cartridges makes it a no brainer...Now to find a good shop that can do the work in a reasonable amount of time!
