I have a "ding" on the slide of my 3at, it almost looks like it took a hard fall onto something sharp, but I can see that it's clearly been blued over. It could have been there when i bought it, but I don't remember seeing it. I know I haven't dropped it or anything. I guess my question is is this something that could be covered by warranty? Obviously it doesnt really affect the function. It's slightly deeper than it looks, but just barely. I was also thinking about getting it plated by Jack, I was wondering if you think it might smoothen out from the sandblasting.
