I have not heard anything about how the spent brass looks. On my late model G19 test fire date 10/10/11, with the stock recoil spring, my fired brass shows a mark on the rim at 3 o'clock From the extractor and then a small dent about 4-5 o'clock from what appears to be hitting the bottom of the ejection port. There are also brass marks left on hood of the slide. SS recoil spring eleminated this. I have the 336 ejector and non updated recoil spring. This was with Winchester WWB. FWIW
