what do you think ?,was even thinking if it was a longer barrel I

The only S&W barrel that fits the criteria is the 59xxTSW barrel (40xxTSW sized with a 9mm bore) but it is 4" long.
I have considered turning the bell end off in the lathe and a new bell welded on and shaped at the 3.5" point.
Or, as you say, machining a ring and shrinking it in place.
That would allow for threading the end.
I don't have access to a 4040 barrel, but the 9/40 TSW barrels have a more vertical cam lug angle than the base model variants, so that would need to be determined, although I suspect the 4040 barrel cams are the same as the TSW.
Another bit of info, the slide bore for the barrel bushing is the same for the 9/40, but the bushing is pressed in place so swapping the bushing back and forth would be a problem, even if you could find a 9mm barrel.
Another thing, base model 9mm barrels are thicker at the base than 40 barrels so they must be narrowed to fit 40 frames.
A few years ago the 59xxTSW barrels were more available than they are now and that can make the conversion difficult.
A lot more involved than just slipping that CS45 top end you sold me on my CS40, swapping the magazine, and shooting the combo!
