I know some are .40 and some are 9mm but they share the same frame.
Here are the ones I know for sure:
6906, 6904, 6943, 6946 all can swap mags and grips. I have heard some 40s can as well but I don't know what the model numbers are. I wish S&W would made their pistols harder to understand with the model numbers.
