Somebody was watching the full frame pistol portion of the Magpul Dynamic Handgun? I think I remember Hayley discussing this. Is this your reason for wanting to do this or is it your personal preference? I would recommend the Warren tactical sights, I've used a pair on a 1911 and found them to be highly accurate (that and it was 1911) Only issue is they can only be installed by gunsmith only.
I use Trijicon Night sights, because in high stress situations, you will align three dots and pull the trigger. I know Costa discussed aligning the dots in the wrong order, but honestly your focal points on the sights make this hard to do, and with proper grip and practice, your eyes lock to that front post on your presentation and follow it right to your sight picture. To counter act it you could also get yellow or red rear sights to alleviate this problem.
I am really just picking your mind. I'm just a big advocate of having three big bright dots so shooters can make on target positive hits in high stress situations.
