Climbhard Posted November 29, 2018 Share Posted November 29, 2018 I’ve put a new Gen5 G34 together to play in CO and honestly I’m not getting the accuracy I’d expect from it. Shooting with the dot at about 15 yards I’m getting a 3-4” group. I’m gunning an 11 pound recoil spring and wondering if this is adversely affecting accuracy? Gun unlocking early? I’m resting on my range bag. It’s not me. Link to comment Share on other sites More sharing options...
rooster Posted November 29, 2018 Share Posted November 29, 2018 Just because your resting on a bag doesn’t mean your doing it right. I have a g34 gen 3 and I suck at bagging a gun on rests. I’ve tried and tried and I actually shoot better freestyle. A 3 inch group at that close a distance doesn’t seem right especially off a rest. A lot of shooters run 11 lb springs but the majority 13. Don’t know if it would have an effect on accuracy but their cheap so try a 13 and see. Maybe get another shooter that’s good off a bench and see if your groups change. Could even be your load. Just too many variables to get a definitive answer. Link to comment Share on other sites More sharing options...
Stymie12000 Posted November 29, 2018 Share Posted November 29, 2018 Try grouping it with the factory recoil spring. I have a gen 5 17. With a 13# recoil spring the slide moves forward about .007" when the trigger breaks. With the factory recoil spring it doesnt move. I've read that with the gen 5 design the recoil spring needs to be stiffer to keep the gun in battery. Now with that said, I tested a 13, 14, 15, and factory. I didn't see any change in accuracy. Pretty much all the same size groups. I ended up with the 13# since it group the best with double tap shots with my load. I do have a 11# but never tested it. But it could be that 11# isnt keeping the gun in battery and accuracy is suffering. So personally I would test with the factory spring! Then go from there!

12glocks Posted November 29, 2018 Share Posted November 29, 2018 I wonder if a stock striker spring is pulling the gun out of battery a bit when you pull the trigger and have a 11 pound recoil spring. I can run 11 pound springs in our Gen 3 34's but our Gen 5 34's are real sluggish going into battery with an 11 pound spring. If you know that test where you point the gun up pull the trigger and see if the slide will return to battery when cycling the slide. My wife had the first gen 5 and got the slide cerakoted. It definitely would not return to battery performing that test. My gun has the factory finish and I never tried the 11 pound spring. I just went 13 across the platform after that. I don't like being that close to the edge. The slide has more mass on the gen 5 34's is my theory on why it needs a little stouter spring, plus your may have a little more weight up there with a dot. We run reduced power striker springs as well. Link to comment Share on other sites More sharing options...
HoMiE Posted November 29, 2018 Share Posted November 29, 2018 I found that since the gen5 recoil rod is slightly longer, the traditional recoil spring does not preload as much as you go to lighter recoil spring weight. The ismi flat wire spring seem to do a better job of closing the slide with lighter weight. Link to comment Share on other sites More sharing options...
Climbhard Posted November 29, 2018 Author Share Posted November 29, 2018 Thanks for the comments. To add more detail. 11 pound spring is an ISMI and striker is 4.5. I can shoot a one hole group of the range bag with my limited and SS guns so I don’t think the problem is me. Link to comment Share on other sites More sharing options...

I subscribed to the thread so please do report back your results with a little stiffer recoil spring. I am using ISMI springs as well. I have the TTI grandmaster kits in all our 34's now so the striker springs are definitely not stock either. Link to comment Share on other sites More sharing options...

We run reduced power striker springs as well. I tried it. Pointing it up and racking it after a trigge4 pull and yup, doesn’t go into battery. Also I’ve got the weight of the Delta point to contend with so I think 11 is just too light . Even hand cycling I would describe it as “sluggish”. I will swap it out for a 13 and see if there is a change. Unfortunately, I’m leaving the country for a week and it’s winter here so I may not be able to test it form quite a while. When I do I’ll report back .. Link to comment Share on other sites More sharing options...

Xanatos903 Posted November 30, 2018 Share Posted November 30, 2018 I'm surprised nobody has asked whether you've tried different loads. Even out of a pistol at short range, not all loads are created equal. Link to comment Share on other sites More sharing options...
Jamese35 Posted December 7, 2018 Share Posted December 7, 2018 I have a gen 4 d34 with a 11 pound spring that shoots great groups with most anything I put in it. But I get really good groups with a bayou 145, 2.9 grains of tight group. I was getting about 2 inch groups at 25 yards. (Benched) lol. They some other loads and see if that helps.

Did you change your striker spring to a lighter one at the same time? If not that could be your problem. Link to comment Share on other sites More sharing options...

Climbhard Posted January 4, 2019 Author Share Posted January 4, 2019 It’ll be 70 this weekend so looking to get some range time in and get this sorted out. Going to try factory Ammo with stock recoil assembly and taking the deltapoint off. See if it’s the gun or me and my astigmatism Link to comment Share on other sites More sharing options...
