I've tried one bead, two beads, rifle sights but I went to a scope - Bushnell Trophy 1.5 - 4. Since I'm used to a scope on other guns it was the way to go for me plus as you get older you won't see as well as you once did. The eye relief is good and has never been a problem. I have one on my Beretta 12 ga and 20 ga.
