He is right.

I have fit barrels of unknown origin onto frames and it almost always takes a bit of yutzing.

I go out looking for a barrel and simply can't find a direct replacement. Even barrels made by the same manufacturer but at a different time are not the same.

So I settle for what I can get. Remember....There are a lot of ASP and ASM revolvers out there and the parts are not made any longer. There are also vendors who will tell you they have ASP and ASM replacement parts but the really don't.

Then I try to put it together and find that, for example, The gap is way to wide. Or the depth of the arbor hole is too shallow. Maybe the distance between the locating pin holes is off. Or the lug is thicker than the frame.

This is stuff that is very difficult to do with an electric drill and a file.

If you are set on proceeding with this project, you have made a wise choice to use a Pietta and I would add, it should be a very recent one. Parts interchangeability is better.
