You might be able to do it, but you'd need to get the face of the cylinder machined to accept the moonclips. You'd then be able to use .357 and .38 special with moonclips even if you couldn't use 9mm.
Remember that while the 9mm and .357 bullets are almost the same diameter (.355 vs. .357 nominal diameter), the cases are different. The 9mm is a tapered case, whereas the .357 is a straight wall.
Rhino and dice dealer are correct. You do not want to try to load and fire 9 mm in a SP 101 chambered in .357. Get some speedloaders and practice. A revolver cylinder has to be machined to accept full moon clips.
