Anybody got any ideas? Joe idea: sharp edge of striker hole in breech face is shaving brass from your case head during feeding/extraction, as the cartridge casehead is being dragged across the breech face itself. possible action #1: gently radius the edges of the striker hole in the breech face. possible action #2: the piece runs fine. Leave it alone and just clean the striker channel at routine intervals. I will check my striker channel tonight for similar brass shavings... will post results for your reading pleasure...

Sean Gaines Posted January 28, 2007 Share Posted January 28, 2007 you might also look at the belling in your case, if you are over belling the case it will leave brass shavings. Link to comment Share on other sites More sharing options...
Chuck Merriam Posted January 28, 2007 Share Posted January 28, 2007 I had an SVI that was shaving the brass cases on the edges of the barrel ramp in the 5 and 7 o'clock postions. Just rounded the edges witha file and polished. Problem gone! Link to comment Share on other sites More sharing options...

No brass residue at all, just black sooty residue. Also looked at breech face and striker hole... it looks like the edges are radiused very slightly. I don't know if it came from the factory or if the original owner did it. I am the second owner. Link to comment Share on other sites More sharing options...
HSMITH Posted January 28, 2007 Share Posted January 28, 2007 Put stock springs back in it and shoot it, I would bet a donut and a cup of coffee the shavings stop. Link to comment Share on other sites More sharing options...
big_kahuna Posted January 28, 2007 Share Posted January 28, 2007 (edited) Put stock springs back in it and shoot it, I would bet a donut and a cup of coffee the shavings stop. HSMITH, I didn't even think of that, but it seems to make sense. If I understand you correctly, then: light springs may be allowing premature unlocking the slide is moving rearward and the barrel dropping while the case is containing pressure pressurized case is forced hard against breechface during movement case+pressure+slidemovement=shaving brass off casehead Is this the idea?

ParaJoe Posted January 28, 2007 Author Share Posted January 28, 2007 possible action #2: the piece runs fine. Leave it alone and just clean the striker channel at routine intervals. Out of sheer laziness this seems to be the best option. I'm going about 1500 rounds between cleaning as is so that will be the new interval. Now if I can count that high is another story.

Sc0 Posted January 28, 2007 Share Posted January 28, 2007 That's my experience with my Glocks as well. I think that somehow the brass is being shaved by the extractor, maybe while chambering a round from the mag... It's now a cleaning point as when I did have Glock malfunctions it was due to he brass buildup inside the striker/extractor/firing pin block channels. This was with the factory recoil springs and aftermarket ISMI. Link to comment Share on other sites More sharing options...
BlackBuzzard Posted April 17, 2007 Share Posted April 17, 2007 For what it's worth my G34 gets a lot of brass shavings in the channel too. Its got all aftermarket springs. Also, a used G35 I just picked up (still had the copper paste on rails) and cleaned up real good had significant brass in channel too. Impressive analysis a few posts back.......with striker hole shaving the brass on case. BlackBuzzard Link to comment Share on other sites More sharing options...

I don't know if it came from the factory or if the original owner did it. I am the second owner. My HP did the same thing. It was "primer flow" back into the hole in the breech face and then sheared off as the case was extracted. Every time I sprayed cleaner after shooting it looked like I had panned for gold. Look at your fired brass and see if the primer face has a "sheared" or "wiped" appearance. The fix is to "radius" the firing pn hole in the breech face a touch.

Glocks tend to be very hard on brass from the standpoint of shaving those little chips. What you're seeing is normal. It causes no real problems. Ignore it and drive on. Put stock springs back in it and shoot it, I would bet a donut and a cup of coffee the shavings stop. I'll bet it doesn't. It happens even in totally stock Glocks.

David Sinko Posted April 18, 2007 Share Posted April 18, 2007 My 35 runs exclusively on a diet of plated bullets which are crimped significantly enough to begin to remove shavings from the mouth of once fired brass. The gun has never ever failed to chamber a round and the brass shavings get everywhere inside the action. I haven't cleaned it in over 5000 rounds and it still performs flawlessly.
