Got a better result that any aftermarket part would have given us, anyway, but that is just another one of those subtle "Harrison things" that I was referencing earlier. He reprofiled and serrated it, then had the Trijicon folks do their magic before re-installing and blending it to the slide.
I also really like the way in which the night sights present as a result, since the rear tube is nested quite deep, and provides just enough illumination to drive the eye to the front without creating any visual confusion in the stacked configuration. Not something you would necessarily think to spec intentionally, but a highly-effective solution nonetheless.
