Using an OEM firing pin, I would like to hear your experience with reduced power striker springs. Hopefully you will have 100's, if not more than a 1,000 rounds through your reduced power striker spring report.

Here is my report. Wolff 4.5 lb striker spring. 3 failure to fire over about 1,200 rounds. One round was a CCI Blazer Aluminum, one a WWB 115 gr round, and one Federal Champion 115. Spring was swapped twice. One had about 900 rounds the other about 300 rounds. Failure to fire on both.

I have now upgraded to a Wolff 5.0 lb spring. No misfires so far at about 150 rounds. FWIW, I use a 13 lb RSA and need a reduced power striker spring to balance things out.

Glocks don't hit primers very hard even with the stock spring.

You already saw what happens with a lighter spring. They don't work well.

 

[Glock+2]

with a 4# or 4.5# striker spring use a lightweight striker...

 

[BelieveNglocK]

My glock has never failed to fire any ammo I have put through it.

 

[Makoman]

Why not just keep it stock? Was the factory set-up giving you issues?

I'm using a reduced power striker spring with a skeletonized striker from Zev Technologies (Glock 19 gen 3). I had a couple light primer strikes at first after I installed these items but after a few thousand rounds all is well.

During the major ammo scare after Sandy Hook, I acquired 5,000 rounds of Federal Champion 115's. They just do not eject well with the stock 17 lb RSA and heavier Glock 34 slide. The 13 lb RSA cures that but the firearm will not pass the RSA lockup test. A 5 lb striker spring seems to be just about right, but my round count isn't that high yet.

If I had it to do it all over again, I would have gotten 5,000 rounds of Blazer aluminum. Cheap and runs great.

Fired 200 rounds today, 100 was under the clock, with the 5 lb striker spring. No issues at all. The best part is I knocked down the 6 plates and 5 pins at 38 feet today with one shot each, so the extra half pound spring didn't have a negative effect on accuracy.

13 lb RSA and 5 lb striker spring may just be the ticket for my 34 Gen 4 and wimpy Federal Champion 115's.

I don't see the connection you are making between the spring on the striker and the RSA. Why do you think they are related?

The striker spring and RSA work against one another. If the RSA spring is to light and the striker spring is to heavy, the action will not reliably close. Add the extra weight of the Glock 34 slide and it's a real balancing act.

At my last IDPA shoot, one of the shooters on my squad had several failures to fire. He was running a stock striker with a 4# spring in his 34. I run a 4# in my 34, but with a modified striker and a 14# Wolff spring. No problems here.

Most competition shooters in my area who have lightened their striker spring to get a better trigger pull will use Federal primers. I have 4 or 4.5 pound (can't remember) striker springs in my 17 and 34 (with stock strikers) and use Federal primers with no issues whatsoever. When primers were scarce, I used some CCIs, and had an occasional fail to fire. Have now gone back to the Federals, and the guns are running 100%. It's my understanding that Federal primers are relatively soft and CCI primers are hard, and that has been my experience.

You reduce the trigger pull by about 12 ounces for every pound you reduce the striker spring. It's OK if you match the striker weight to the striker spring. It's not OK if you use the stock striker.

 

[usnret]

I run a 4.5 lb striker spring in my open 34 with no problems. And I use Winchester primers.

Well they work against each other to keep the gun in battery. However, reducing the recoil spring down to 13 lbs doesn't mean that you have to reduce the striker spring to keep it in battery.

 

[Duck of Death]

Thr stock firing pin CAN be used if it is lightened.

My 34 Gen 4 fails the RSA spring test big time with stock striker spring and 13 lb RSA. I'm using a Jager polymer guide rod and ISMI spring. It passes with a 5 lb Wolff striker spring. This is the test I am referring to.

I still don't get it.
When I pull the trigger to the rear, I don't see how the RSA is doing anything. When all the safeties are defeated the striker is free to fly toward, still don't see how the RSA is doing anything.

Now the gun goes bang and the bullet leaves the barrel. As the barrel unlocks from the block and the slide moves rearward I see the RSA compressing, don't see the striker spring doing anything, does it? When the compressed RSA drives the slide forward how does the striker spring come in to play? Finally the gun is back in battery due to a functional RSA. How did the striker spring work against the RSA?

Thanks

Remove your RSA and put the slide and barrel back on the frame. Because the striker is at "half cock" for lack of another word, you will see how the striker spring is resisting barrel / slide / frame lockup.

I put in a Ghost kit, it included a 4lb striker spring. This was too light. In the end, I went with a Wolf 5lb Spring.

The Ghost 4lb usually struck the primmer good enough, but not always. The real problem was that it was fighting with the trigger spring, keeping the trigger just past the trigger safety (back inside trigger guard area). This was unacceptable. I worked with Ghost, and got a new 4.5lb striker spring. And later found that the surface where the trigger safety rubs, had not been machined (inside trigger guard area), and it had to drag on that rough surface. After I sanded the surface where it rubs, it stopped hang up there (w/ 4.5lb Spring). In time, as the spring settled, the only thing that corrected this was to reinstall the OEM striker spring (6lb). Unfortunately, this resulted in too heavy of trigger pull, for me.
I purcheast and installed a Wolf 5lb spring. This was just right.
No failures of the trigger safety, and no soft hits on the primmers, and ~4lb trigger pull...
