Just about the time I turned 50 I decided that night sights weren't such a bad idea.
Flashlights are great, but the night sights are always ON when negotiating dimly and/or erratically well lit houses, hallways, attics, basements, garages, etc., etc.
The standard 3-dot tritium capsules are okay for me, but I find the dot-over-dot & dot-over-bar combinations to be excellent & fast acquisition sights for low light use ... again, for me.
I've never cared for the different color combinations I've tried, but I realize that some folks DO like them. That's cool ...
My only complaint with some tritium capsuled sights is that the "thickness" of the white paint around the tritium capsules is a bit inconsistent from one set to the next, and naturally isn't as easily visible in "normal" indoors/outdoors light conditons due to its thinness compared to solid white dots. Fortunately, it can be resolved to some degree by the proper application of white sight paint as the original paint wears & thins.
I like the Big Dot front sight post for the bright white synthetic "ring" located around the tritium capsule. I can see it in my peripheral vision while the weapon is still quite a bit below my line of sight. I only have the Big Dot on an off duty .45, as I like to retain the potential for making an accurate handgun shot out to 50-75 yards with my service weapons ... and the Big Dot doesn't seem to lend itself to easy use at ranges much beyond 10-15 yards. Not quickly, anyway.
I like brass beads on my large revolver's front sights ... and my 5-shot revolvers have bright neon orange sight paint applied to the serrations of the front sights periodically. It works very well for my eyes.
I still find the regular 3-dot (white) sights to be okay for many circumstances, but they're just a bit less distinct than they used to be.
Plain black sights apparently aren't as practical for me as they used to be ...
