I have a Millet Red Dot scope on myRuger Super Redhawk 44mag. and I am really happy with it. It has a 3 moa dot. Note: dot covers about three inches at 100yds. It is fastsight picture due to no power and accurate. It has a reistate with 11 setting for brightness. It has held up with heavy 320gr. wfln hard cast handloads pushing 1320fps. My hunting partner has one on his Ruger Super Blackhawk Bisley. I even use one on my Ruger MKII 6-7/8" side slab 22LRhandgun and have Taken ground squirrels about 80yds. This is another option to a powered scope.
