Replaced Firing Pin Spring Problem - Glock 17

[kszaid]

Hey everyone, hope you're all having a great weekend. Last night I installed some new parts on my gun. A Taran Tactical Ultimate Springs Pack and a Taran Tactical SS Guide Rod. One of the springs in the spring pack is for the firing pin.

The ammo I shot today was Jack Ross reloads. And before you say thats the problem, know that I have been shooting JR reloads for a very long time without any problems. I picked up two 50rd boxes. Of those two boxes I had about 6 or 7 fail to go boom.

At first I thought maybe I reassembled the firing pin incorrectly? Maybe it was the rounds and I got a bad batch? Or maybe the whole spring set esp the firing pin spring needed breaking in.

Has any one else had problems with rounds not firing when they've replaced their firing pin spring? But when the gun did go boom, the trigger pull was smooth as buttah baby!

Thanks!

Put the stock firing spring back in and see if the problem persists. I'm not a fan of changing the firing pin as I can get the trigger weight plenty low without it, but I know people on here who are very knowledgeable who do the firing spring mod. You may need a titanium firing pin to go with lighter spring. I just leave that whole mess alone.

It all depends on the type & brand of primers. Some need a harder strike. Your firing pin spring is too light for the primers being used.

Your options are a heavier firing pin spring or different primers. That's it, simple as that.

What's the point of installing the springs? Seems like a headache waiting to happen.

update: I kept the rounds that did not fire and told the range guys about them. One of them just told me he as well had 3 dead rounds from a 50rd box. Sounds like they got a bad batch of Jack Ross. He took the rounds from me and they also did not fire in his completely stock 17.

So much for your flawless reloads...

Here's a free tip: after you mod your gun, be sure to go out and test fire with reputable, factory ammo. Do you really need more variables when testing?

If those reloads have Wolf primers then you need a stock striker spring. I was given some Wolf pistol primers last year and I had a few light strikes with my Glock 35 converted with a 40-9 LW barrel. It does have a light striker spring. Off the bat I knew there wasn't enough power to the striker as my accuracy was affected with inconsistent primer strikes. Chrono showed my velocity had a wide extreme spread. Switching to the OEM striker spring lit those primers with excellent results.
