De nada.

FWIW, the ejectors and firing pin safety plunger levers could come in either plain stainless or black finish/carbon steel, depending on the time and vendor, as I recall. I've gotten both types at various times over the years when I've ordered new parts, and I've got both in my various guns.

Ditto the extractors. Sometimes when ordering from the LE parts contact I'd be asked if the finish/color of the part mattered to me, as they might have one in stock but the other back-ordered, apparently.

In the slide stop lever & manual safety assemblies, the newer parts were either plain "white" or black, but were both stainless MIM. One was just given a blackened finish after final machining.

I sometimes forget some of the details I've been told at various times over the years.
