Severe Pitting on byf 42

And here's one more that shows even more of it. About the only thing else I might mention is that the left grip is a bit loose. I've read someplace in my searches here about using an "O" ring or something like that with the grip's screw. But I'm not sure if that would help, as it appears to wiggle the most at the top. After close examination, I see that the left grip also has a little movement too.
