Another difference is early 39-2's have a safety lever that's close to the frame, in order for the safety lever to clear the fatter 59 frame early 59 frames were releived under the safety lever.
Since this meant extra machine work and they wanted 39/59 slides to be interchangeable they eventually changed the safety lever to stick out further so it would clear the wider 59 frame without relief cuts.
