I have an 835 that I presently have a Bushnell Trophy Red dot (1x20) for POA/POI issues. I have been thinking of getting a reflex (red or green) sight. I see that most of the reflex sights are 1x20 sights. My question deals with light gathering. Since both sights are 1x20's, does the reflex sights gather more light especially at daybreak during flydown? I feel the Red dot's only fault is at first light. The Red dot has NO zero issues, even with 3 1/2 inch Hevi's, and has put plenty of birds in the bag. Pro's and Cons would be Greatly appreciated.
