Bumping this to add a note regarding the Trijicon XD front sight which features a yellow photoluminescent-painted ring around the tritium. It's not a feature I mentioned because it seemed like a pointless gimic seeing as the sight will almost always be inside a holster inside clothing... It's never going to glow when you draw it.
I did however find one scenario where it kind of helps... Transitioning from sunlight to shadow. It's not a scenario I see myself in with this G42 but it can happen IRL, maybe, somewhere to somebody.
