I'm planning on getting the Ruger Single Six in blue with a 4" barrel. My gun dealer says they also have the anniversay Rugers with the fixed sights in the shop as well. I had planned on just getting the Single Six because I'm picking up the 92FS Brig and probably will only have enough for standard model. My question though is how is the fixed sights different from the adjustable sights that come on the Single Six model? Is it still a good gun in comparison to the anniversary revolver?
