new guide rod

[hybrid]

can anybody help me coz i installed a new guide tungsten guide rod on a glock 34.. i also bought a new spring for it but it seems that the spring isn't that strong to bring the whole slide back to its original position when it cycles.. any suggestions on how to correct this? thanks...

12# is too light, 14# should function but you'll probably batter the gun to death.

Heres a test we can do. With the magazine out rack the slide slowly and slowly bring it towards battery, before lock up let the spring do the rest of the work (hold the slide). Does the slide go into battery?

Also, what brand springs did you buy? Factory spring weight is usually 17#. Lighter spring weight is for reduced loads. If you got a 17# spring in the spring kit run that weight.

Good luck.

As stated above, the factory spring weight is 17 lbs. Why use anything less, if you are shooting factory (SAMMI spec) ammunition. The slide weight is tuned for 17lbs. Using less will cause premature wear and allow the slide to batter the frame. I use a tungsten guide rod on both my 17 and 34. They work flawlessly with a 17 lb. spring.

The only reason I would consider changing to a different spring weight would be if I was shooting a large volume of +P+ ammunition. I would then consider going to a heavier spring weight, perhaps 20 lbs, or so.

Keep in mind that Glock pistols were designed and developed for Military use - - to meet NATO spec. NATO spec 9mm ammunition is a bit hotter than SAMMI spec commerical 9mm ammunition. NATO spec 9mm is very close to SAMMI spec +P ammunition.

If the spring isn't closing the slide you can have an out of battery discharge which can damage your gun and your hands. Or you can get light primer strikes which will fail to discharge your round. The tungsten rods really offer nothing except some weight up front, which shouldn't matter if you're holding the gun properly (especially on a 34).

If you want to check and see if the spring is strong enough then do this.

Make sure the pistol is unloaded, point the muzzle straight up, pull the trigger, now with your finger still on the trigger, bring the slide back and then ease it forward. Once you get 1/4" from the slide being close let it go. If the gun does NOT go into battery, the spring is too weak. If the gun DOES go into battery then the spring is fine.

Honestly, I'd just run the factory spring, they work fine, and if they break a new one is $8 or something.

alright.. i ordered a stock weighted spring.. wish me luck and hopefully this works!.. thanks!

Did you test your old spring like I mentioned? If so, did it fail to go into battery?

[hybrid]

yes.. and it seems that the spring fails.. thanks..

I just learned something cool here, to embarrassed to say what though!

OK, share it - - we can all learn from each other. What did you learn?

Please explain how you can have an OOBD. A Glock will not fire when out of battery.

Yes it will.
