Not entirely, but when I called a few minutes ago to make arrangements to have a slide shipped to them for their NP3+ finish, I was informed that they will not be accepting any civilian guns for work any more, and after September only manufacturers & government entities will be able to get metal finishing performed.

This sucks. I've got a Glock 22 slide that's at least 15 years old with their original NP3 finish, and it still works as good as when I received it originally. The resistance to wear, self-lubrication, and corrosion resistance were worth the cost to me for a duty gun that's constantly exposed to the elements.
