I just bought a sig p239 last week. I brought it home cleaned and lubed to Sigs specs. I went to the range the other day and shot 50 FMJ. Only firing 50 rounds this barrel really marked up quick. Especially on the bottom corner of the chamber. Here is some links so you can see what I am talking about. The mark is smooth and shiny. Is this normal? Should I be concerned. My M&P's barrel never looked like this and it had alot more rounds through it. Thanks in advance.
