Zev Extended SS Guide Rod in G24

[lucky #7]

I just got a Zev extended ss guide rod for my Limited Division G24. At the same time I ordered a 15 lb ISMI and a the 14 lb "red" Zev spring. I tried the ISMI for 140 rounds and it ran fine, but I have since read that the ISMI springs will eat up a metal guide rod pretty fast. Inspection after using the ISMI spring showed very little wear on the Zev SS guide rod because it was with so few rounds, but I could see marks on the rod where the "groove" wear would begin. I read that the round wire springs don't wear the groove in the metal guide rods. So now I'm going to try the Zev 14 lb spring.

1) Do any of you have any experience with the Zev springs with regards to performance and reliability in the G24 or G35?

2) What do you guys think about the ISMI springs chewing up your SS and Tungsten guide rods?

I have a tungsten rod in my G35 along with an IMSI spring. There is definite wear that started occurring after fairly few rounds. I think the new springs have a sharper edge on them so the wear happens faster at first. So far, it hasn't caused any functioning issues; but I'm prepared for it to start happening at some point in the future. I'm probably going to buy another rod soon just to have in case.

I bought the Jager full length guide rod and 14lb zev spring for my G34 and have no signs of

wear on the guide rod after 2000rds. I have since got a G24 and put that same assembly in it with no problems.

I think it's time to replace the spring though due to paint starting to

chip off...gonna order a few more.

Thanks, I'll ditch the ISMI spring immediately in favor the Zev. My only regret is that I didn't trust my instincts. I knew I should have just used the Zev from the beginning, but I thought ISMI was the safer bet because the stock spring is flat. I guess there is a reason why Zev recommends their round wire spring.

I only shot 140 rounds with the ISMI spring so it didn't appear to inflict any damage to the rod other than just some very light marks out by the front of the spring, but they didn't eat into the steel. Just very light visual marks that can't be felt when running a finger over them. Continued use with the Zev spring will likely polish the rod anyway eliminating any visual evidence that I ever used the ISMI at all.

edited to add that my initial inspection of the Zev spring revealed that it appears to be very high quality. The red powder coating is really well done, and it is built to pretty tight specs.

Lastly, do you guys have any concerns about lock up with the Zev. when vertical the pulling the trigger does pull the slide back. No movement happens when the slide is horizontal. How important is that test?

I have the ZEV tungsten and ZEV red spring in my Limited G24 and ut works great. Nice and smooth recoil

I don't know about there others here, but I have never had any issues. I am currently running the Zev tungsten guide rod in my limited G35 over an ISMI 13 lb spring and I have had zero issues. There are no wear marks and no indication of any issues whatsoever. I would say that I have put over 8,000 rounds through this gun with this setup. And that is a conservative estimate.

One thing I have noticed when trying the Zev springs: They feel kinda spongy and "stickier" than a spring that isn't coated. Not saying that is a bad thing, it just felt weird to me so I quickly went back to the flat coil ISMI which isn't coated. I am going to eventually give the springs another try and see how they do once my current recoil spring bites the dust.

For info only: Wolf springs will not work with the Zev guide rod, it's just a little too tight of a fit.

Sorry for the double post, I have no idea what happened?

That test is very important and the slide should NOT move when held vertical and the trigger is pulled. IMSI and Wolff springs are wound on different diameters so the proper diameter guide rod is essential.

I didn't like how the Zev felt when I cycle the gun. I had a red one, not sure the weight on it at this point. I've tried an ISMI 13# and 15# with my 24 and settled on a 13.

Limited 24 has a 13# IMSI & Tungsten rod, Open 24 has an 11# Wolff with Jager extra extended guide rod.
