I just took delivery of a new Stainless 856 Defender with 3in barrel on 25Oct2023 and it is already showing signs of scraping or "scoring marks" around the matte black cylinder after only shooting 12 rounds through it. Analysis of root cause clearly shows it is the Cylinder Stop that is marking up the cylinder. For such a good looking revolver, I am very disappointed to see that it is only likely to get worse! Has anyone else experienced this and/or contacted Taurus with concern? Thanks, USNCWO3Ret
