hysupra Posted January 7, 2014 Share Posted January 7, 2014 (edited) Testing new open gun build, first day I shot 20 9mm major rounds without an issue. Made more of the same ammo and another box just a tad hotter. Maybe 25% actually fired, the others all light striked. So is it the gun or the ammo? I checked a firing pin and it's fine. I'm wondering if I didn't seat the primer well enough. I changed the firing pin spring back to stock, so maybe it'll hit harder. The trigger pull is now a lot heavier because of the spring change. I'm using small rifle primers and they seemed to all be seated flush.

Rick88 Posted January 7, 2014 Share Posted January 7, 2014 Since you went back to a stock spring I'm sure it will work fine now. If you really want the lighter pull with the lighter spring you will need an extended striker. Link to comment Share on other sites More sharing options...
hysupra Posted January 7, 2014 Author Share Posted January 7, 2014 I have the jager in now and have never had a problem. It's weird that it works great one day and the next its a pile of poop. That's what leads me to believe it was the ammo. Link to comment Share on other sites More sharing options...
fishhunter3 Posted January 7, 2014 Share Posted January 7, 2014 I use the light springs on my open glock and it's 100% with 6.8 AC and CCISR primers but I am using a ZEV extended and lightened striker may be difference Link to comment Share on other sites More sharing options...
Whitefish Posted January 8, 2014 Share Posted January 8, 2014 In my experience, the light strike issue may be with the small rifle primers, primarily because of the harder primer cup. An extended striker may help with the issue, but switching to small pistol primers may help as well. Link to comment Share on other sites More sharing options...
Sarge Posted January 8, 2014 Share Posted January 8, 2014 Check to see if the tip of your striker broke. Mine broke off on the first Jager I bought and they replaced it free and all was good. Link to comment Share on other sites More sharing options...
hysupra Posted January 8, 2014 Author Share Posted January 8, 2014 Nope it's still there. I think it's just this batch of ammo. The striker sounded weak when hitting the primer, but fine when the gun was unloaded. I'm thinking the primers weren't seated correctly and the striker couldn't get enough momentum to set it off. But... All the primers seemed flush. Should they be buried a tiny bit? Would match primers help? Link to comment Share on other sites More sharing options...
openclassterror Posted January 8, 2014 Share Posted January 8, 2014 Match primers aren't thinner, they are just more consistent in the amount of priming compound in the cup, and some have a different anvil. If the indent is light, match primers won't help. Link to comment Share on other sites More sharing options...
hysupra Posted January 8, 2014 Author Share Posted January 8, 2014 Ya the indent was light. Even after hitting the same round 3 times. It's just weird that it worked flawlessly the day before. Link to comment Share on other sites More sharing options...

j0s3ph Posted January 9, 2014 Share Posted January 9, 2014 Make sure your pistol is going to full battery. It can happen when using a light recoil spring and light striker spring. With your pistol empty, pull the slide all the way back and release the slide. Don't pull the trigger. Now check to see how much tension the slide has when lightly pulling back your slide. If it feels like the slide can easily pull back and fall out of battery, then you will need either a heavier recoil spring or a lighter striker spring. i had this dilemma when i built my Open XD.

hysupra Posted January 9, 2014 Author Share Posted January 9, 2014 I have a 13# in it now. It's tight. I'm going to put the zev spring back in and see if it was the ammo this weekend. This gun also recoils pretty hard with 6.5 of autocomp. I'm using a carver 10 port comp as well. Link to comment Share on other sites More sharing options...
Keepkool Posted January 9, 2014 Share Posted January 9, 2014 10 port comp ?? I have just finished up my Glock 34 / Carver setup. just starting to work up a load. I keep stove piping but I still at 145 PF. with a 124 mg with Titegroup. I need to find some auto comp to try. Good luck and keep use up to date.

gerritm Posted January 10, 2014 Share Posted January 10, 2014 What striker spring do you have in it? I have a Bobby Carver built G17 open gun that was set up for major. I went to a 11# recoil spring for lighter loads and I tried a 4# striker spring with a stock striker and had many light strikes with various brands of ammo including my reloads, nothing was consistent, would fire 10 in a row of the same stuff and then not fire one or two and the primer would have a dimple in it. I tried a 4.5# spring and it improved greatly, but still had some light strikes with some Winchester 9mm Nato rounds and some of my reloads. I went to a 5# spring and all is good, gun runs like a top. Fires everything I run through it. I just got a Zev skeletonized SS striker and put the 4.5# spring on it will try that next time at the practice range. gerritm Link to comment Share on other sites More sharing options...

Kraj Posted January 26, 2014 Share Posted January 26, 2014 It should be marked on the bag the parts came in? My zev kit came with a 2# spring and a 3# spring. I get some light strikes with CCI SPP with the 2#, the 3# runs fine Link to comment Share on other sites More sharing options...

Glock 17 with 3 ports on top ad 2 on the side, 11 lb recoil spring and 4 lb firing pin spring with zev 2lb connector, stock firing pin. There are times I get light strikes while sometimes it just runs really great. I will now try a heavier firing pin spring (back to stock spring) and I am 99.9% that it would eliminate the light strikes however, I can already feel a heavier trigger. Apart from purchasing the full zev trigger kit, is there any other remedy to achieve a light trigger but eliminate light strikes? Link to comment Share on other sites More sharing options...

That's the only way you can really use the 4lb striker spring reliably. I prefer Jagers light weight striker, but Glockworx makes one also. Either of those two.

dskinsler83 Posted February 3, 2014 Share Posted February 3, 2014 It is hard to get 100% reliability w/ a light striker spring and standard striker. the elusive SA feel of a glock trigger and light 2-2.5lb break can come with a price guys. like using federal primers only. the trigger system HAS to travel to work, it is how it is designed. an extended striker helps and ensuring that the striker gets plenty of travel to compress that spring and then let it slam forward with its momentum to set off the primer. I tell everyone no matter the striker and no matter the spring weight and no matter the brand of primer, be sure to SEAT THE PRIMERS AS DEEP AS YOU CAN CRAM THEM.

BoyGlock Posted February 4, 2014 Share Posted February 4, 2014 (edited) How does an "extended striker helps and ensure that it got plenty of travel to compress the spring"? I thought the extension is on the tip? Edited February 4, 2014 by BoyGlock Link to comment Share on other sites More sharing options...
