Big Norm -
Have to agree with you (mostly) that the chipout underneath the safety lever is "not repairable." I say "mostly," because I have an authentic Navy which has that area of the left grip repaired. It is not observable from the outside and looks almost perfect, but the inside is a very different picture. See attached photo.
The image below is a closeup of the repaired area. Because the repair is probably old (or made to appear old and dirty) and most likely recheckered, at least in this area; it appears not to be damaged. Knowing that it has been repaired, the abnormal straight front side on the safety lever cutout is a dead giveaway.
