Rock GI slide, Remsport 9mm ramped barrel, Stealth Arms alloy frame.
Function is excellent in every way as far as shooting, but its making microscopic brass dust. Becomes evident by choking the firing pin channel and giving light strikes.
Collected some brass and examined, expecting to find an extractor problem. Basically no mark on the brass around the extractor (20% of brass has a mark at the front where the extractor nose needs to be shortened by stoning), a beautiful ding on 70% 80% of the brass showing where it hits the ejector ... but the entire back of each case is scuffed. No mark on the frame, but a heavy brass residue on the back of the slide, patterning the case and primer, but no motion.
Timing problem or head spacing problem?
Arrows are pointing at the dings made by the ejector, showing this is "upright" Extractor marks occur on 20% of them at 4 o'clock as seen this way. Most have no extractor mark, some I can't see the ejector mark, while all show the verticle scuffing.
