    Hi Everyone,

    I bought the 40 s&w conversion kit for my M9-A1 from CDNN a few weeks ago, and, while I was cleaning the barrel, I noticed there was a scratch on the inside of the barrel. It's perpendicular to the rifling. I'm relatively new to firearms, and the M9-A1 is my first pistol. Is this scratch bad? I haven't used the the barrel yet. Is it ok to use or should I call SAI?
