I suspect that once some gunsmiths start offering these option some shooters will be balking at the cost of a new barrel shroud if that's what is needed to achieve what is wanted. BTW, I would love to have a 6 inch 620 with a tensioned barrel, so I've done a bit of thought experimenting on what would be involved. Quite simply, the barrel shroud would run into a pretty good chunk of change if you want it to look "factory". Lots of seperate profiling operations and fixtures to take a raw bar of steel and make a shroud that looks correct. Then there is the matter of finding a 6 inch barrel, that length would require a custom barrel. In total I suspect that the cost would probably run to about double what a brand new 6 inch 686 would cost.
Going shorter on the other hand would be relatively simple. All you have to do is cut the shroud back, square off an prep the muzzle end, then cut the barrel and re-thread it to fit. So, at some point we may see 3 inch 620's being created, however I don't think that a 6 inch 620 will happen unless S&W decides to do it.
