I recently picked up a G19 gen3. Went shooting and put about 100 rounds through it. After the range session, I came home and cleaned it with solvent and brass bristle brush. Then a brass jib with cotton square on top

After which I notice what seems like a scratches about 1" from the crown.

It was hard to take a macro shot with enough light and not wash it out. But you can sort of make it out. It doesn't look pitted to the naked eye, just a discoloration.

Wondering if it is something I should worry about. Hard to see how I would of scratch it with a brass brush and brass jib. I used a pro shot cleaning rod:
