If you liked the tritium front on your Dawson/Sevigny sights, I think you'll be pleased with the plain rear/FO front combination. I've been running a Sevigny rear/FO front setup on my G34.3 for about . . . a long time (I want to say since about 2006 or so) and it has served me well. About the only change I've considered making was going to the Dawson adjustable rear, but I don't shoot near enough competitions anymore to push myself to make the change.
