I love my Williams universal rib sights on my 930 turkey - some know that I've had various optics on the gun in the past but the Williams Firesights are really versatile and do everything "well" - in competition I've had all variety of shots including clays on fly and a versatile sight is a must. They keep me in my class as well.MikeD said:I've got a set of Williams Fire Sights on a turkey/deer barrel for my 500c (22" Vent Rib) and I've got a set of magnetic Tru-Glo's that I used on my 930 when I got my last turkey with it. I'll try to post some pictures.
