I really liked the Wilson Combat battlesight, so I went with their front fiber optic as well. The sight picture is nice, and I've been happy overall. Even my gunsmith commented on how quickly he can pick them up, and he teaches defensive shooting classes and used to shoot competitively.
I have several hundred rounds through it with the sights, and I don't have any complaints. I would imagine you could find a tritium front sight to go with them, but never looked, I like fiber optic.
I also use their sights on my Glock, with similar results.
