Iirc the internals changed with the introduction of the lockwork my guess has been thats why they needed to change the frame shape to make room for the lock hole.
If I'm wrong and the hammer trigger etc from a 629-5 Mg is exactly the same ( except in case color) in theory they could stamp it a 629-5 but thats only a theory.
They can't with the 686 because of the new ball detent alone.
perhaps. though I do have a performance center 629 that has the ball detent and is marked 629-6.
