Dead in is right on the old 3 screw revolver transfer bar safety recall.
Arjay is right on about the next owner not knowing.

Around 1960 a fella was practicing the fast draw with a Ruger single 6. He shot his foot and threw the Ruger over a rocky Missouri ridge putting a small bend in the trigger guard. He sold it to Dad to pay his ER bill.

He had done a Bubba trigger job on it. The pull was measured in ounces not pounds. Dangerous. Dad wouldn't get it fixed because he believed it enhanced accuracy.

The last time Dad and I went fishing on the RI er I took the Ruger. The trigger pull was down to nothing. When I inherited it the first thing I did was send it in for the transfer bar recall. They sent the original parts back. I've since thrown them away.

It is still accurate even with the lawyer heavier trigge pull. I feel safer. Most companies today void the warranty if one changes out specific parts. I've owned quite a few Ruger autos over the years and liked them but none ever made me want to keep it.

If it was me I'd take the non factory parts out and get it fixed.

The lawyers and Ruger desire to put out an excellent product should be applauded.
