Is this a damaged crown?
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.

Just load that puppy up and shoot it,
Its not a target pistol! it's an up close and personal protection assistant.

A brass cleaning brush is not going to damage the rifling. I always run a brush thru in both directions, and I still shoot as bad as always, but no worse. It's not a problem with the rifling!

Too blurry to tell, but a few dings outside of the barrel will not affect the shot very much on a pistol.

It looks fine. However, unless you have leading that you need to remove, I would recommend a nylon bristled brush. They work fine for normal deposits, and will not in any way damage the barrel. I always err on the side of caution, as long as it's getting the job done.

You sratched off some of the bluing, thats all. \
After a hundered or two shots, the gass cutting action will do the same.
besides, as said, the gun, IF used, would most likely be at bad breath distances.

I have a Remington 581 that I've been shooting since the last days of the Carter administration. Up until about 10 years ago I cleaned it crown first with a brush - then I read about "ruining" barrels. Still shoots better than I ever will.
I suppose if you are a silverback gorilla and you have a steel rod and diamond brush, you'll destroy that crown quickly. However, I've yet to see a mere mortal armed with an aluminum cleaning rod and brass brush and exercising due care destroy a barrel by cleaning crown first. Not saying it can't happen - just sayin' carbon steel is a bit more patient than we are.

Not a problem, won't affect the operation of the gun.

No. You cannot damage your steel gun barrel with a bronze or brass bore brush.
And the steel used to fabricate the bronze/brass brush is annealed wire and that is far softer than your barrel steel also.

Its a pistol- not a target rifle. Scratches or gouges be damned. Shoot the piss out of it. You won't notice any muzzle damage causing a measurable effect on accuracy.
