I don't like being a killjoy, but I'm afraid I'm with DWalt and Art Doc on this. I have had and have M&Ps with stock damage, notches, and stock damage that looks like notches, maybe even stock damage intentionally made to look like notches, in that area, particularly on ex-police guns that spent a lot of time in open holsters. Could indeed be anything or nothing.
