Brass deformation???

GT, I helped a similar problem my Stainless Houston Luger displayed. The rims of the ejected brass all had a triangular "karate chop" mark, along with a slight burr raised by its striking the corners of the slots inside the barrel extension. I marked the rounds to index them and discovered that the shells were striking the left side.

I removed the extractor body for closer examination and noticed that its claw was not symmetrical, and a little longer on its left side. I went easy with a needle file and evened them up a bit. Although this seemed to steer the situation in the right direction, I quit filing as soon as most of the cases made it out unscathed, or with perhaps only a mark small enough to be ironed out during reloading. Replacement stainless steel extractors are in the same category as hens' teeth, as you know!
