I went to a new range last night with a friend from work. The range had very low lighting over the shooting booths. With my old/bad eyes I had real trouble sighting on most of my pistols. I want to add night sights to at least one of my HGs. I already tried glow on to the factory sights and it is not good enough. I figure upgrading the MP 45 is best as that is my HD piece. So what are the pros and cons of Trijicon vs. Fiber optic sights? Can anyone recommend a particular brand? Any tips for installing? Thanks for any help you can give.
