No, the chambers have to be reamed to accommodate the 9mm case because it is tapered. It is larger in diameter at the base than a .38spl.Can you just have an LCR cylinder scalloped to take moon clips and shoot 9mm through it?
I have a S&W 360J that has been rechambered to 9x23 by Pinnacle High Performance. The conversion has worked out great for me.
