Logante,
The grips on the S42 are Italian made grips that were available in the 1950's-60's and are very well made repro grips, much better than most of the ones available now-a-days, they usually fit very well. The ones on the DWM look like modern ones. I may have a pair or two of worn original grips or repaired refurbished grips that will fit one or both of your guns....I will have to check and see.
