These will ONLY fit the FIRST model of Ruger Blackhawks ("Flat Tops") and Single Sixes made up until 1962 with the XR3 frame. I have handcrafted these American elk grips with nice matching character. They are sized for an average to large hand and have an excellent fit to the frame. They are shown on my 1957 mfg Single-Six . You will be pleased or simply return them for a full refund. They are $140 shipped to the first "I'll take them". Payment by check, MO, or Paypal "friends".
