Yes. It is fundamental to the design.

A shrouded barrel divorces the angle that the barrel is tight from the point the sight is vertical, in that they are literally on different parts. Or perhaps that was your point.

I don't happen to own any shrouded barrel revolvers, but the other claim, often made by Dan Wesson, is that the barrel tube is now in tension, supported only at the ends, and of consistent round cross-section. This results in more consistent "ringing" of the barrel, similar to how rifle designers are always worried about the bedding and free floating of barrels.

I can't shoot well enough for this theory to make any difference to me... Some have claimed that shrouded barrels more frequently come loose. I have never seen any hard data on this, which only a gun manufacturer would have from warranty, so it may not be true.
