Dimensions are all different and the .38 Super has a SAMMI max pressure of 36,500 PSI as opposed to a .38 Special +P max pressure of 20,000 PSI.
You might succeed with .357 Magnum chambered revolver but why risk it? Just put FBI +P loads in the 642 as they will stop anything on two legs that a .38 Super would stop - and do it cheaper.

I really agree with the safety concerns expressed here. I don't think the .38 Special +P is the equal to a full house .38 Super, the Super has a significant energy edge. All things being equal, more velocity/energy in the same weight slug means better terminal performance. Don
