Hello, I recently purchased a Glock 19 gen 5. I have owned my firearm for a little over a month. I just fired it for the first time last night. There are visible marks inside my slide and on my barrel. My barrel and slide were both oiled properly. I don't know what to do about this, I am very concerned. I don't want to continue to fire it and have the situation go from bad to worse. Does anyone have any thoughts about what I should do about this or what caused this to happen? I am rather new to gun ownership, so I have no idea if this is normal or not.
Thank you in advance,
Bob Brock
