I have owned xs big dots on several pistols and my old eyes love them. That being said I am looking at the i-dot pro's or the hackathorn's for my g17. While they still have that big dot (orange outline) up front I like the rear sight on these.
Just as soon have the hack's without the tritium in the rear but if I find them with the price close enough I will go for the i-dot's.
