theglockman34 Posted March 15, 2017 Share Posted March 15, 2017 i have a glock 34 with a double diamond barrel and compensator, zev trigger, sjc microdot mount., slide racker etc. the guns barely ejects and idk what to do i got a lighter spring and idk what to do i am running 6.5 grains of hs-6 115 grain fmj with seller and bellot primers and i have tried everything and cant get it to eject right any suggestions Link to comment Share on other sites More sharing options...
superdude Posted March 15, 2017 Share Posted March 15, 2017 maybe you need more gunpowder to create a stronger recoil impulse. The compensator will seriously decrease the rearward motion of the slide. try more HS-6, or if you want the same power factor try a powder that requires more weight for the same velocity, such as Accurate #7.

jcc7x7 Posted March 15, 2017 Share Posted March 15, 2017 Not to burst the bubble but My open 9's won't make Power Factor with 115gr bullets with that amount of HS-6. Are you making 165+ Pf with that load? IF you're not sure, get to a chrono( yours and friends , somebodies) Before you get overly concerned make sure your load is what you think it is. If your running a minor load it may explain the lack of strong ejection. Then go down to a 8-10 lbs recoil spring. I'm running a 12lbs spring (34) for CO at minor so I'm confident running an open gun you can go much lower. My 2011's are running 7's and 8 lbs springs for 9 mm major. just some thoughts that might help Link to comment Share on other sites More sharing options...
theglockman34 Posted March 15, 2017 Author Share Posted March 15, 2017 is it ok if i start to get a square on the primer are those pressure signs concerning or just minor pressure signs that i should proceed with causion Link to comment Share on other sites More sharing options...
mro111lland Posted March 15, 2017 Share Posted March 15, 2017 My open gun would not even try to cycle with that little powder switch to federal rifle primers and u need at least another grain and half to make it run Link to comment Share on other sites More sharing options...

It matches the cut in the slide breech face. That's how people can tell ammo has been fired in a Glock. What power factor do you want your ammo to achieve? Minor or Major? If you want Major power factor, you'll need to increase the powder. You'll also want a chronograph to check bullet speed since that determines power factor.

JMike Posted March 15, 2017 Share Posted March 15, 2017 Definitely use a chrono to work up your load. You have been given great advice thus far. I would also look at running a 124 gr bullet vs the 115 gr. I'm not saying you can't do it with a 115 gr, I'm just saying everyone I know that is shooting 9mm Major is using the 124 gr. Good luck to you! Link to comment Share on other sites More sharing options...
RippinSVT Posted March 15, 2017 Share Posted March 15, 2017 I would recommend getting the extended ejector as well, it helped my Open 34, but mostly for consistent ejection pattern. I also took some weight out of the slide and run a 9lb spring with Major loads. Link to comment Share on other sites More sharing options...

With a 115 you will be closer to 8.5-9.0 gr of hs-6. Of course don't try this without a chrono and start low and work your way up. Depending on your oal, you could barely or not be making minor pf as well. Link to comment Share on other sites More sharing options...
theglockman34 Posted March 16, 2017 Author Share Posted March 16, 2017 thanks guys she runs great and the ejection pattern is consistent with 8.2 grains of hs-6 with a pf of 172 Link to comment Share on other sites More sharing options...
Bullets Posted March 16, 2017 Share Posted March 16, 2017 Did you switch to 124 gr bullets? Link to comment Share on other sites More sharing options...
Part_time_redneck Posted March 16, 2017 Share Posted March 16, 2017 I just retired a 34 from open as I picked up a used Infinity. LW barrel, SJC 11 port comp, 11 lb recoil, factory weight slide. Experimented with 115's & 124's with 3N38. I liked the 124's with 8.3 g loaded at 1.140. Made @ 170 PF. When working up even at @ 165 ejection was iffy. Once PF went up ejection issue took care of itself. I also switched to a U-die, seemed to help with feeding. After these changes gun ran 100%. VV & WAC are all I've tried and fell in love with 3N38.

theglockman34 Posted March 16, 2017 Author Share Posted March 16, 2017 no i didnt i have 5000 115 so thats what im sticking with reguardless of that the gun runs great thanks for your imput guys gun runs fantastic Link to comment Share on other sites More sharing options...
RippinSVT Posted March 16, 2017 Share Posted March 16, 2017 (edited) I used WAC and made major in my 34 at 7.2gr with a 115. The extra barrel helps. Edited March 16, 2017 by RippinSVT Link to comment Share on other sites More sharing options...
