So I come asking for help on my M&P .40 FS and I hope you all are up to the challenge. So my concern arises following my latest range session (Shot 165 rounds of both 180 grain HP and 165 grain FMJ) while cleaning and inspecting my firearm afterwards when I notice some, what could be, unusual wear towards the end of the barrel. See attachments.

If you could all do me a favor and check this spot in your M&P barrel and let me know if this is present on yours as well, just to give me some assurance. I have attached some pictures below to try to capture to the best of my ability the "wear" marks I am talking about. Thank you in advance.
