wyomingballer Posted May 12, 2018 Share Posted May 12, 2018 I need some help. My 9mm is have a problem ejecting. The brass is turning backwards and not ejecting. The weird part is that this only happens after cleaning... 3-4 jams in the first 50 rounds. After that no issues at all. This happens with a standard extractor and with the aftec...

jpl Posted May 12, 2018 Share Posted May 12, 2018 The extractor is not hanging onto the empty case. Try more tension. Link to comment Share on other sites More sharing options...
ChuckS Posted May 12, 2018 Share Posted May 12, 2018 Find someone to tube your ejector. 9mm and upright scope mounts are difficult to get to 100%. You are close! I gave up on vertical when the best I could get was 1 jam every other match. Link to comment Share on other sites More sharing options...
38super Posted May 12, 2018 Share Posted May 12, 2018 At first glance, I'd say we were being punked. Look for ejected brass marks under the scope mount. It's a combination of ejector length and extractor. tension. Link to comment Share on other sites More sharing options...

It's a combination of ejector length and extractor. tension. And also the profile of the ejector tip. I doubt we are being punked as I had the same thing happen during my upright mount trials. Sidemore and keeping both eyes open ended my trials. Link to comment Share on other sites More sharing options...
Sarge Posted May 12, 2018 Share Posted May 12, 2018 Take the scope mount off and try it. If it runs 100% then you know where to start. Link to comment Share on other sites More sharing options...

Just hope it will work out at area 1 next week.Sent from my Pixel XL using Tapatalk Link to comment Share on other sites More sharing options...

Don_B Posted May 12, 2018 Share Posted May 12, 2018 There are 2 pages on "9mm extractor tuning" started Arpil 10 about this same thing. It probably has everything that would be put on your thread. Not all parts are drop in. Even the Aftec may need to be tuned. Link to comment Share on other sites More sharing options...

Bkreutz Posted May 12, 2018 Share Posted May 12, 2018 I had my gunsmith "attempt" to tune mine to work with a horizontal CMore mount, didn't work 100%, the end result was that it was decided that the only way to get complete reliability was to separate the cases by headstamp and tune the extractor/ejector to that particular brand of case. I decided that that would negate the reason for 9 major (cheap/free brass), so I installed a 90 degree mount, end of problem. Link to comment Share on other sites More sharing options...
Broncman Posted May 12, 2018 Share Posted May 12, 2018 I had the other thread awhile back. I could never get 100% Got about 1 in 200 or about one a match. I made an offset mount that moved the cmor over .225" of an inch. That thread is in the gunsmithing threads. Ejector profile to keep brass from hitting the hood low and bouncing back into the CMore as well as extractor tension we're the biggest help.

cferree Posted May 14, 2018 Share Posted May 14, 2018 I tried a sideways mount several years ago (the smith who built the gun couldn't tune the ejector/extractor for 9 major). The gun ran but, I didn't. The mount/C-More blocked too much of my field of view. Sold the gun, bought a SV IMM, no issues. I bought a Match Master year and a half ago, and had the same issues your picture shows (and others). Bought a DPP and it resolved the issue, until it failed (Leupold replaced it, traded it for a 7.5, and it failed). I reinstalled the factory mount and slide ride, read a lot of posts on resolving ejection issues with 9 Major, and discovered I went the wrong way with the ejector. Joey Hardy (smith who built shorties in the 2000's called the Mongoose), put a 5-7 degree cut on the ejector to ensure the brass ejected low enough to clear the scope. I tried duplicating his tune and failed. I read several posts stating that the brass could be ejecting too low, hitting the bottom of the ejection port and then bouncing into the mount. I'd bought several ejectors to experiment with, so I reversed the cut. It worked. I'm now 8-10K rounds without any FTE's. Don't give up or be afraid to try something unorthodox.

Broncman Posted May 15, 2018 Share Posted May 15, 2018 (edited) Try an offset mount like a Cheelie. Does not block your view like a sideways mount.. got to keep my slideracker as well. Edited May 15, 2018 by Broncman Link to comment Share on other sites More sharing options...
