Those were what I HAD on my XD before Carl Jarl killed it. I have tritium sights on it now, and it is great! The XD is an awesome gun! I have a couple different ones and love them all!!! The gunsmith working out of the Bullet Hole (I don't remember his name) is awesome. He did an outstanding job for me. He put the sights on that I bought (don't buy them at the hole - they are EXPENSIVE!). However, when he called me about the gun, he said that he would suggest only putting the tritium on the front sight and leave the back sight black, that way your eye automatically zeroes in on the front site. When I do my other guns' sights, that's what I'll do.
