Picked up a new Gen 4 26 last week. (I really missed owning this great shooter) I had a Zev Spring Kit (with 3.5 connector) put in. The trigger weight is now about 4.5 lbs, and feels good! The only problem is the trigger safety does not reset 3/4 of the time.
After doing a bit of searching, I found that replacing the stock striker spring resolved the issue.
Just wondering if anyone else has experienced the same?
Fwiw, I have a Lone Wolf U.A.T. on the way. After trying several other aftermarket triggers, I found this one to work the best.
Btw, this will NOT be a carry pistol. I currently carry a 42 with a Ghost connector. The trigger weight on the 42 is 5.5. lbs.
I installed a Zez connector in my G26 and it fail to reset the trigger all together, I tried adjusting the angle and it did not help. From my research it is not frequent but it happens so I took it out and replace it with a Ghost edge and problem solved.
This particular time I did it on my own, while I'm not a gunsmith I worked on several of my guns and my brothers also with success but I do have a gunsmith that helps me and works on my firearms.
I haven't used a ZEV spring kit, but I have had other brand light striker springs hamper reset. Going back to stock striker spring weight has always solved the problem.
Also try a different weight trigger spring. I had this problem with a 4th gen g17 and I had to use a different trigger spring. Not sure zev even makes it anymore.
The trigger spring is what holds the trigger bar out of reset, it works against the striker spring. Replacing the trigger spring likely won't have any effect on the failure to reset, unless the one in the gun is not installed properly and binding, in that case, just making sure it is installed properly should fix the problem. A lighter trigger spring which balances the forces employed in reset may help when using a light striker spring, but then your trigger weight will go up some, not sure how that compares to just the lighter striker. Of course with a lighter striker spring, if you don't go with a skeletonized striker, you can start getting light strikes on harder primers. And so it goes.
In any case, I have found stock trigger groups to work well enough, the more I shoot it, the smoother and lighter it gets (to a point that is good enough for my limited shooting skills).
It's a balance, for sure. Some changes are made for direct results, and some are made to balance other changes. Ideally, they all work together.
For my purposes, the main mode of trigger weight adjustment is the striker spring. My normal gen3 G34 arrangement is OE minus connector, #3.75 striker spring, #5 trigger spring, #12 recoil spring, tuned OE striker, Federal SPP, 130PF ammo. I have over 200,000 rounds on that setup with no light strikes, no reset problems, and no other function problems. A #2 trigger is easily achieved.
If you want a 100% reliable #2 trigger with anything other than Federal SPP, you have to get a little more creative. If you're willing to go up to a #2.5 trigger it's a lot easier to get 100% reliability.
My idea of 100% reliability is cleaning the gun every 10,000 rounds and not having to replace or re-tune any parts for 40,000 rounds/1 year.
Probably true, but I am of the mindset that each little thing adds up. When I practice with the #2 spring for example, I see a measurable decrease in the size of my groups over the #3. Not a LOT, but "some". "Everything adds up", I always say.
having said that, the zev kit with the #3 spring is still super good. Light pull, crisp, short reset. It's still freakin beautiful.
The difference between a #2.0 and #5.0 trigger doesn't have much impact on my ability to shoot offhand groups. The difference between a #2 and #3 trigger has no impact there at all.
On fast transitions, the trigger weight makes more difference, but still not that much. The main difference is on faster splits. I need a 2 pound trigger to shoot consistent 0.20 splits.
So for Steel Challenge, there's no difference for me between a #2.0 and #2.125 trigger. But for a high hit factor stage when I can shoot at or beyond the limit of my ability to fully track the sights, I need the #2.0 trigger to get the best results.
With iron sights, going below 2 pounds does not make much difference. 0.15 splits are about the fastest I can consistently work a dry 2 pound trigger without getting freeze.
I don't care about crispness - only overall weight and a fast enough reset to stay ahead of my split time.
