Thank you all for the replies. The markings are on the side of the slide. I inspected the barrel and found no markings. I will be contacting CS to see what my next step will be.
Just an update. I contacted CS about this and they said I should send it in for further inspection. Waiting now on packaging info. Again cant thank you all enough for the info. Really glad to be a part of this group
Did you send pics or just describe the issue?
Glad to know that this does not affect the operation of the gun. It does bother me seeing them. Will post results once news from CS comes back.
