I've seen a very odd situation involving a Dan Wesson in .44 Magnum.
The owner found he could no longer get the barrel shroud off.
The barrel had bulged in several places locking it into the shroud , which had matching bulges.
How this happened I don't know, only saw for a moment it while a gunshop owner was examing it.
Could have been excessive pressure handloads.
To remove the barrel for replacement they would have to cut away the barrel shroud.
As to most durable I'd also recommend the S&W revolvers.
