I have just observed 4 straight scratch lines on the barrel of my 3913 when it is viewed from the ejection port. Further examination revealed a burr or raised area in one of the shallow grooves underneath the slide with the barrel removed. I am thinking the burr is making the scratch lines when the pistol is fired. Would it harm or mess with the alignment of the slide and the barrel if I try to smooth the burr down or should I leave well enough alone. What would be a good method to smooth off the burr? I purchased the 3913 used and have only fired a few hundred rounds through it and just now noticing the scratches.
