I probably grossly overthought this.
So I started this year by putting together a Roland Special. For that I did a set of Ameriglo sights with a tritium front, green outline, with a plain black rear. Since I usually go with high-visbility front sights and plain rears, I figured I’d try something similar. (In retrospect, it turns out I was having issues aligning the front and the rear in the dark well enough to pick up the dot with my glasses off.)
Then I got laid off and decided to sell the Roland Special to help keep myself afloat while I decided what I was going to do.
Now that I’ve been back at work for two months (doing the same thing for someone else for about the same money, but working more hours to get that money), I had decided to put together another red dot’d Glock, this time sans the comp. But I couldn’t determine what I wanted to do for sights and went back and forth between the Ameriglo sights I had used before, the Ameriglo all-black sights, and the Trijicon tritium sights. I ended up ordering both the three-dot Trijicons (with white outline front, black outline rear) and the Ameriglo all-black sights… because I had initially ordered the Trijicons and changed my mind and tried to cancel the Trijicons, but it was too late by then, so I ended up with both (and the Ameriglos were only ~$50 delivered).
Installed the black-on-black Ameriglo sights. Got the draw and presentation down pretty well in daylight. Having since discovered that my previous belief that I couldn’t pick up the red dot without my glasses on was erroneous, I decided to do some draws and presentations in a window-less basement room of my house (which I have just done today).
Result? Pretty consistent on the dot with both hands, but not very consistent with one-hand (whether strong or support) (with little difference between presentations with and without glasses one). Use of a hand-held light improved the consistency, but the room was bright enough I would probably be able to positively identify a threat without the use of a hand-held light, the light might not be a pre-requisite to employing lethal force in similar lighting conditions - while still being dark enough that I could not pick up on my blacked-out iron sights.
So I decided to swap out the blacked-out Ameriglos for the Trijicons. And taking the gun back down to the basement, I had an immediate improvement in my ability to pick up the dot (as - I think - my subconscious brain aligned the tritium during the pistol’s presentation) in both strong- and weak-hand-only presentations. The white outline for the front sight also seems to help with my presentation in brighter light, too.
I do wish that the Trijicon sights were a little bit shorter (like the Ameriglos), as I prefer the irons to be in about a lower-1/3 cowitness, while the Trijicon sights seem to be more of a lower-3/8 cowitness.
Still, I do not find the Trijicon sights to be bright enough to cause issues with picking up the dot and I do not find the sight picture to be too busy in either daylight or darkness. So that’s where I have ended up, for now (I may replace the rear sight with one that has blacked out yellow or orange lamps - or maybe use a red Sharpie to dim the rear lamps somewhat, hopefully not so much that it makes them unusable).
