I just recently cleaned this gun using a brass brush. I pushed it through from the breech, but then I did pull it back out the other way and kinda scrubbed it a little bit. I thought this was OK with a brass brush. Did I damage it?
I can't say that I ever really looked at the crown before now, and it just struck me that those scratches looked a little irregular. Could just be normal. This is off a Ruger LC9.
