I have had this old Ruger pistol for over 40 years. I lost the rear sight and called Ruger. I explained that it was about 40 years out of warranty, that I carried it with me on the tractor while bushhogging (rough treatment,) and I hoped they still carried that part for such an old pistol. They sent me a replacement, must have shipped that day because I got it quick! No charge! That's customer service!
