Which do you prefer, and why? I'm looking at a set of Trijicons for my Kimber. I'm leaning towards the Trijicons, because I can get them in 2 color, and they're $20 cheaper than the Meprolights, but carry the same warranty. I like the idea of a yellow front sight against green rear dots. I don't even see that as an option with the Meprolights.
