Back to you: What type/manufacturer of magneto on what engine
installation?

The answer varies from magneto to magneto and installation to
installation.

For instance, I can't recall ever doing a manufacturer-mandated (as
opposed to FAA mandated) 500 hr inspection on a Slick magneto that
couldn't use a set of new points and the crap dug off of the
distributor block.

I can't recall ever doing a 1000 hr inspection on a Slick magneto that
didn't need a set of new points and a new distributor block.

Unless prices have changed a big bunch, you can't buy a new set of
points and a new distributor block + an hour or so of labor for much
less than the price of a new Slick magneto.

I would really not get into the practical maintenance requirements for
a dual Bendix/TCM magneto, given a choice.
