This is the sort of thing that will always garner differing opinion.
For me, any change from stock decreases the value of the gun, unless as has been pointed out, the work was done by a known gunsmith. Maybe unfair, but that's the way it is.
There are a lot people doing more to their handguns today than people in the past wouldn't have dreamed of.
Personally, I won't buy a revolver or pistol that someone has done any internal work on. I'm sure I lose out on some well done handguns, but it's not a risk I'm willing to take. Other people will feel differently.
