My 600 safety began failing this summer. I had problems 30+ years ago, and had a Canjar replacement installed and resolved the safety being positive, but still no bolt open feature. So this summer when the safety would not at least stop the trigger I had to choose: 1) Call it good, toss it in the river because selling it to find its way into some kids hands would keep me up nights. 2) Fix it. As the rifle has a Shilen barrell, a Brown Precision stock, shoots lights out, and has earned its place in the safe by being the first rifle for various friends kids, girlfriends and wives, fix it was the decision. The Gentry 3 position has only been in for a couple months , but it looks like a solution at this point. Worth it? In my circumstance yes.
