I don't think Ruger ever had a "bad run" of Redhawks. I have a 7.5 inch SS Redhawk with an Ultra Dot red dot sight mounted. Bought new in 1983 I think. The gun had a little more play in lock-up then I like, but a good trigger, so I figured I would try it. I don't know how many thousand rounds later, still seems a little loose, but the gun shoots like a house a fire with almost anything I feed it. It has accounted for wild boar, a black bear, whitetail bucks and does, coyote, and all sorts of lesser game, including grouse and rabbits for the camp pot. Figured out a long time ago its to big for hip carry, but just fine in an accross the chest rig.
