For a little clarity, I've shot some defensive and USPSA matches (indoor) that had dark stages. My night sights did help solely because while we shooters were mostly in very dark areas, the targets had at least SOME backlighting. I suppose we could see those conditions in real situations but it's probably not as likely as most would think. I'm still thinking about getting a fibre optic front sight on my new carry gun which is useless in total darkness. I really haven't made up my mind yet. With a light just about any type sight will work. I think bright green, yellow or orange front sights every bit as good as a tritium and if you have both (think Trijicon HDs and some Ameriglo) you'll likely never see the tritium in defensive use. You'll just "go" when you pick up that color and probably miss that glow in the middle completely.Point taken. Thank you.
