Thanks for the thread resurrection, Allen.
I've not forgotten about it, and have been doing diligent research. I'm leaning toward a three dot system, probably with an orange or yellow front and and green rear arrangement. Even with a three green dot setup, getting the front dot misaligned, at close quarters center mass point of aim, would inflict much hurt.
I've looked at Trijicon, Ameriglo, Truglo, and Meprolight. Apparently, Ameriglo is owned by Trijicon and uses Trijicon tritium vials (for the moment's lack of the proper word), but make their own bases, thus they are same-same. Meprolight advertizes its close relationship with law enforcement and the military, which goes a long ways, with me.
I've various sights sitting in Midway, Brownells and Amazon shopping carts.
