I bought a Glock 17 Compensated used for a spectacular deal. I have the overwhelming urge to upgrade everything I buy so that takes me to my quesiton. I hope to never need to shoot at night but I would like some new sights that are better in the daytime but could also shoot at night if need be. I like the TRUGLO Tritium sights and I've heard good things about the HiViz. What do you think? BTW, I want to replace front and rear.
