Just got my s9-a1 NIB and i noticed cycling rounds that they are being scarred heavily by the rail underneath the slide. anyone else have this issue? the brass has 2 parrellel scrapes running down from base to mouth, and it goes pretty deep too. very troublesome, haven't fired any live rounds though.
I just went out of my way to try and scar the brass and it did scar the brass, but I pressed heavily on the brass against the rail and it marred the casing.If they are that bad, take a sharpening stone and lightly smooth out the rails. Don't take a lot of metal off, just what you would after sharpening a knife to remove the fine wire on the edge.
Do the cases show any signs of potential failure after firing?
Probably left over microserations from the machining process.I remember that my first Steyr chewed the hell out of brass, but that tapered off after I put a good number of rounds through it. Oddly enough, my second M9A1 was never as bad as the first about that.
