As I get older, my eyes continue to get weaker, and being able to get a proper sight picture on my pistols gets more difficult. I have looked at several different types of after market sights such as XS and Hi Viz, but am not sure what I should get. I want something that will assist during day light hours as well as in low light conditions, and I think some of the sights are only good during day light hours. Any suggestions based on what has worked for some of you?
