mike g35 Posted October 10, 2013 Share Posted October 10, 2013 What weight recoil spring are you guys running in your 34's for shooting minor PF in production? What weight bullet are you using? What's your power factor? . Link to comment Share on other sites More sharing options...
theKenny Posted October 10, 2013 Share Posted October 10, 2013 13lb IMSI captured 124 JHP or 147 gr plated 135ish PF I do not reload but buy from an ammo manf. I just tried Automatic accuracy's economy ammo and it is nice. Link to comment Share on other sites More sharing options...

mike g35 Posted October 10, 2013 Author Share Posted October 10, 2013 Thanks guys. I ordered a few 13# Wolff, 14# Wolff, and a couple Glockworx 12# springs to test. I have a 15# Wolff in there now but I think that's a bit heavy for my minor power factor loads. I figured asking was fine but testing would be better.

TCWriter Posted October 10, 2013 Share Posted October 10, 2013 I'm running an ISMI #13 spring on my G34, shooting mostly 147 gr reloads at 900 fps or so. Tried the #11 and it didn't seem like an improvement with the match ammo -- and it was a big step backwards shooting factory ammo. Thinking of buying a #16 and trying it, but haven't tried yet.

uod Posted October 11, 2013 Share Posted October 11, 2013 I run a 12lb ZEV recoil spring (the blue one, uncaptured) in my G34. I'm shooting 124gr. Montana Golds w/ 4.0gr of Titegroup sitting behind it. Power factor is around 133-135. Link to comment Share on other sites More sharing options...

mwc Posted October 11, 2013 Share Posted October 11, 2013 (edited) I haven't noticed a diff between 11 and 13 Pretty much how I felt about it as well using ISMI with a 135 PF and MG 124HP. Will stick with 13 for reliability sake. Edited October 11, 2013 by mwc Link to comment Share on other sites More sharing options...

45 Raven Posted October 11, 2013 Share Posted October 11, 2013 I'm also using 4.0 of TiteGroup under a 124 gr. Montana Gold JHP (with the aforementioned 13 lb. spring), and I also don't notice much, if any difference between an 11 lb. spring and a 13 lb. spring.

ZombieHunter Posted October 12, 2013 Share Posted October 12, 2013 (edited) I run a 12lb ZEV recoil spring (the blue one, uncaptured) in my G34. I'm shooting 124gr. Montana Golds w/ 4.0gr of Titegroup sitting behind it. Power factor is around 133-135.Very similar to what I'm considering. Any issues with reliability?I just recently got this setup on my G34 Gen 4 as well - had MAJOR issues with it (no it's not on backwards). It doesn't appear to let the slide go back far enough. There is at least a 1/4 - 3/8" difference in how far it goes back from the factory spring to the Zev rod. I had everything from dead trigger, light strikes, failure to go into battery, etc. with that setup. Switched back the factory spring, and it all went away. Not to mention, there is no way that Zev 12lb spring is 12 pounds (blue one). It feels the exact same as the factory spring. I have an 11 lb wolf spring in another setup, and it's MUCH MUCH softer (like it should be). Even if it did work, I'd be hacked off because it shed blue paint all over everything; was a mess. On top of that, the picture on Zev's web site, shows it to be a captured setup, with a screw. Got it, and it is non-captured, with no screw (not even any threads in the end). Not happy with it at all. Edited October 12, 2013 by ZombieHunter Link to comment Share on other sites More sharing options...

Sean Gaines Posted October 15, 2013 Share Posted October 15, 2013 you can run the lighter springs, just be sure to polish the ramp to a mirror finish. If you are having issues with the lightend springs upgrade a lb or 2. Always lean on the side of reliability. Link to comment Share on other sites More sharing options...
