I have had limited experience using Trijicon night sights on a Sig229 and would like to put something like that on my XD40 SC. Just wondering the differnce between Night Sights and Fiber Optic Sights( if any.) Also would like to get opinions on the Pros and Cons of both. I know the first question people ask is "What do you plan on using these for". The answer is range shooting,home defense and of coures the occasional all out Zombie attack.:shock: Any opinions and/or experience with these sights would be greatly appriciated. Thank you for your time.
