I suspected that the S&W branded grips (stocks) would be okay for the 940 moon clips due to the short length of the 9mm cartridges. I swapped the original (still pristine) Uncle Mike's grips from the 940 with the S&W grips that I had put on the 640-0 (.38 special). Crimson Trace 405 laser grips now adorn the newer of my two Model 442 revolvers; those Uncle Mike's grips replaced the S&W brand grips that I butchered on the 640-1 revolver. The universe is again in balance.
