M&P 45 bore condition

I'm thinking of a used M&P 45. The bore rifling doesn't look like my earlier S&W's (4006). It looks pretty shallow. Does anyone know how deep the rifling should be?

I don't know the exact answer but I can say that it would take a billion and half 45ACP rounds to wear out barrel. Its such a slow low pressure round I would not worry about someone shooting it out. I'm sure its fine.
