Extractor mark on the 9mm brass case, Need help!

Ejectors leave slight marks but that's a divot. There's a burr on the extractor that's cutting into the casings.

I would not worry so much about the casings but about what the load from cutting into them is doing to the extractor itself. Cutting the casings like that is putting an excess load on the extractor hook and the narrow part at the base of the hook.

If it were mine I'd be pulling out the extractor and checking it for burrs on the edges of the hook. You don't want to remove or round the hook itself but the edges on the sides of the hook leading up to the point should be slightly dubbed off with some fine abrasive polishing so they don't feel sharp or grabby like a turned up burr feels like. Once dressed up neatly the extractor won't chew away the brass like that.

If all that sounds like black magic and you're not sure about it at all then look around for slicking up semi auto guns like the CZ and 1911's and Glocks for competition. If you're still not confident find a smith or skilled home shop guy that knows guns that can clean up the extractor so it doesn't do this.

I don't recall if I ever did anything but look at my own Shadow 1 extractor. I know it's been out of the slide a few times to clean out the gunk that builds up behind it in the groove. But I seem to recall that my own extractor was fine. And certainly it does not do anything like you are getting. At most there should be a slight pressure impression that only shows up when the light hits that lip the right way. No metal should be gouged out like you are getting.

Nice macro photo too by the way.....

That is lot of information. I am using this factory shadow 1 in the IPSC. I have no problem to disassemble everything. I rebuilt my 1911 and I am enjoyed doing so. :)... I will check the burrs out. Ha, a whole new project. Good for me. Thank you.
