OP, Your Model 10 has stories I'd love to read about...a lot of character and history there. I wouldn't pretty it up too much, but I would preserve those grips...might be worth enough to buy another gun! Used silicone spray/lube a bit back in the early 70s...it does cause beading, and I don't like it...went back to Marvel Mystery Oil, and in the last 5 years Lucas Gun Oil.
