I have looked around for years for a scope for my ruger 44 that was less than $100. Really difficult to find. I did pick up an Osprey scope for it this summer at a gun show for $80, but I cant tell you if it held up. Got it sighted in and then noticed that I had lost a nut on one of the ruger rings, got that fixed, took it out again and had a hard time sighting it in...the problem was with me, not the gun and scope.
I wasnt going to trust a bushnell or simmons handgun scope on that pistol. Read to many bad things about the lower end models. Originally wanted to go with a dot sight but couldnt find anything in my price range that would match the rings.
