Ruger Safety
Seems to me that 10 or 12 years ago Ruger sent me a set screw for the trigger on my model 77. Seems there was a problem and this corrected it. You might email or call Ruger and they can fill in the blanks. I think I still have the envelope they sent me the corrected part in. I can hunt for it tonight and it will tell me the details.
Best,
Dan Batko
