muncie21 Posted June 24, 2013 Share Posted June 24, 2013 I took my open glock to a local match today....holy erratic ejections batman The gun would not run a full mag without getting a stovepipe looking ejection problem. The spent round was 'extracted', but the extracted round wasn't ejected, which leads me to look at the ejector and recoil spring. Other than trying a .40 ejector, I don't know what else I can do, as my 11 lbs recoil spring is likely the smallest that I can reliably run and I have not seen very many 10 lbs springs. Any suggestions on where to start troubleshooting? Timberwolf frame Lonewolf G34 slide SF trigger housing, with 336 (stock glock 9mm) ejector 11 lbs IMSI captured recoil spring KKM barrel with comp (not sure of manufacturer) Shooting 9mm factory loads (124 & 115) Link to comment Share on other sites More sharing options...
stick Posted June 24, 2013 Share Posted June 24, 2013 (edited) I don't have an open G34 but I put the new gen4 ejector in my Gen 3. I'm pretty sure it 30274. I run an IMSI Spring 11-13 lbs ( don't remember without looking) and a Jager guide rod. Edited June 24, 2013 by stick Link to comment Share on other sites More sharing options...
bulldog009 Posted June 24, 2013 Share Posted June 24, 2013 Did you have the ejection port lowered? I know that Lonewolf says they lower the ejection port on their slides, it still may not be enough. Bobby Carver suggests lowering the Lonewolf ejection port even more to ensure reliable ejection when coupled with his C-more mount, which it looks like you are sporting. You can send him the slide to have it done, or you can request the specs so you can do it yourself. Link to comment Share on other sites More sharing options...
fuentesd99 Posted June 24, 2013 Share Posted June 24, 2013 You are using a Carver mount which your port does need to be lowered just like bulldog said. Once that is done you should be good to go. Also, your comp looks like it is an SJC. Link to comment Share on other sites More sharing options...
muncie21 Posted June 24, 2013 Author Share Posted June 24, 2013 Thanks for the input guys. As an additional bit of info, I've used the Carver mount for several years without issues on both a G34 and G17. When I added the comp, I had a few ejection issues, which I thought I had sorted out, by going to the 11# spring. I recently added the timberwolf frame and now can't get through a single mag without a spent case getting hung up between the barrel and ejection port.

KyalSharpe Posted June 24, 2013 Share Posted June 24, 2013 What is your pf? Link to comment Share on other sites More sharing options...
sousa Posted June 24, 2013 Share Posted June 24, 2013 What is your pf? He said he's using factory loads, so I'm gonna say Minor. I had the same issues at first with my Open Glock. I shoot only factory ammo and have a KKM barrel with the Jager comp. I ended up cutting 4 coils off the IMSI 10lbs spring. After that, no issues at all. I do NOT have the Carver mount though since I'm using a C-More STS. Link to comment Share on other sites More sharing options...
Blcksmk Posted June 25, 2013 Share Posted June 25, 2013 Check about lowering your ejection port since your using a Carver Mount. Another idea is you could order a ZEV Extended Ejector and install and tune it to your gun. I am getting ready to install and tune the ZEV Extended Ejector in my G22 Open gun.

Tuflehundon Posted June 25, 2013 Share Posted June 25, 2013 I'd get a hold of Bobby Carver and have him lower the ejection port for you. He will also tune your gun for you. Not sure how much he will charge since your parts are already installed, he charges $70 to assemble, tune , and test race guns. I have talked to a couple of builders and he seems to be the most knowledgeable that I have spoken to. I have also tried out a few guns he built and they are top notch. He will be building my race gun later this year. Link to comment Share on other sites More sharing options...
KyalSharpe Posted June 26, 2013 Share Posted June 26, 2013 If your shooting factory ammo it is almost always going to fail to cycle. time to work up a major/high minor load. i almost guarantee it will fix the problem. Link to comment Share on other sites More sharing options...
EkuJustice Posted June 26, 2013 Share Posted June 26, 2013 The ejection port should be lowered for the open glocks with the mount you have on it. Also, you factory loads may just not have enough to get the longer slide back with a comp but I would address that after having the ejection port lowered Link to comment Share on other sites More sharing options...

Also, you factory loads may just not have enough to get the longer slide back with a comp but I would address that after having the ejection port lowered I would agree that your issue is has a lot to do with using factory loads. That comp is made to be used with Major PF loads. Carver does make a comp for factory (minor PF) loads and a comp for Major PF loads. You should get your ejection port lowered as well as that can cause lots of issues. Link to comment Share on other sites More sharing options...
shooter.860 Posted June 27, 2013 Share Posted June 27, 2013 I had the same issue but was using an SJC mount, tried all the tricks. Extended ejector, white plunger, NLC indicator extractor, different springs weights. nothing seemed to work - while using a Lone Wolf slide. Switched to SJC sideways mount and their 10 lbs spring for minor. Gun runs 100%. I would send it to Carver as suggested. I see both Carver and SJC glocks run well, but most guys are having the pros tune them up. My open G17 Lone Wolf slide KKM barrel with SJC 11 port Comp. 13 lbs for Major - 10lbs for minor Steel rod Home trigger job SJC heavy mag well SJC Cmore sideways mount with thumb rest Link to comment Share on other sites More sharing options...
Mac38 Posted June 27, 2013 Share Posted June 27, 2013 I second the idea of sending the gun off to Bobby. I have a lone wolf slide on my Open Gun that Bobby built and he definately lowered the ejection port. In my experience comps do not like factory loads. You may not have enough gas to properly eject the shell...... Link to comment Share on other sites More sharing options...
mike g35 Posted June 27, 2013 Share Posted June 27, 2013 I run a 9 major G34 in open, but I've ran one with minor loads for GSSF in the past. Using a 10# Wolff recoil spring and WWB 115gr Q-loads I had good results. Bobby suggests WWB 115gr or PMC 124gr for factory ammo, but you should get good results with any decent factory ammo. I'm not a big fan of the LWD frame. I've heard alot of complaints on them but I have yet to test for myself so when it comes to that I digress.

muncie21 Posted July 21, 2013 Author Share Posted July 21, 2013 I snipped 1.5 coils (about) from the 11 lbs recoil spring. It ran well when I tested it at the range. Going to take it to a match tomorrow and see how she runs under pressure. Link to comment Share on other sites More sharing options...
