I have 3 Single Sixes... well, ones actually a Single Ten. I bought the Ten first. Its a great revolver, beautiful, and extremely accurate. I was shocked when shooting it over a rest, Its as accurate as my Mark II Target. Great balance in the 5.5" version. I then bought a Single Six stainless 5.5" convertible because I wanted something to match my Ten, but shoot 22WMR out of. The new Single Nine wasnt available yet, so I bought the Six. When it arrived, the action was kinda gritty, the gun wasnt terribly accurate, and worst of all, the Long Rifle cylinder would bind up. It would shoot 6" groups at 25 yards, and would always throw one round completely off the target, and not from the same chamber. I kinda put it on the back burner, and decided I wanted to try the 4 5/8" Single Six. I bought a blued convertible, and it was excellent, just like my Single Ten. The balance is perfect with the shorter barrel, and shooting Magnums is a hoot. VERY different gun with the 22WMR cylinder, and a hot Magnum load, like CCI Maxi-Mag +V. I decided I needed to do something about my 5.5" Single Six. I called Ruger, and they said "send it in"... I didnt say anything about the accuracy issue, thinking I just hadnt found a load that it liked yet. 5 weeks later, it was back, covered in grime, long rifle cylinder all dark from lead, and just looking like crap. As I started to clean it up, I suddenly realized that the action was now very smooth. I took it to the range, and the Cylinder binding was fixed. It also now is deadly accurate. It will shoot 2" groups, rested, with open sights, at 25 yards. Its the same barrel, so I dont know what they did to fix the accuracy issue, but they worked some magic, and I didnt even ask for that. I am glad they did, because there definitely was something wrong. They are great revolvers, built to heirloom quality, and I am proud to own all 3.
