Hello everyone. I went to the range today and shot about 120rds. Somewhere in the middle I had a failure to fire. The trigger went click but nothing happened.

It was the first shot off a freshly loaded magazine. I ejected the round and checked it and there were no marks at all. Put it back in the magazine, cycled again and it fired. Never happened before or after. I have about 450 rounds through the PPQ after today.

Have only been using Speer 147gr thus far.

Anything I should look out for it be concerned about?

There were a couple of times where it took some effort to get a round into battery but nothing major (off a fresh magazine). That was more common during the first couple hundred rounds.

Additionally, is it normal to see a glimmer of the bullet case from the side of the ejection port when it is chambered?

Thanks.

Unless it becomes a repeated occurrence I would not be concerned. Misfires and hang
fires are part of firing ammunition. It is inevitable that you will eventually that any manufactured product will have some failures over time. It is what happens from here on that matters. Do not over diagnose one FTF or any other failure. Just shoot more ammo and see if it happened again. If it does, it is time to check the ammo and/or the gun. I think ammo is mostly to blame for FTFs.

Pulled the trigger with the slide slightly out of battery. That'll result in a light to no primer strike.....and when you look at the pistol immediately following this click no bang, the slide is all the way forward. The slide is all the way forward because you pulled the trigger which releases the striker and allows the recoil spring to push the slide fully into battery.

To understand that, you've got to understand that the striker spring is cocked/compressed as the slide is returning forward. The single action sear will catch the striker at a point when the slide is at about 3/8" from the slide being fully forward. Its the slides forward momentum, provided by the recoil spring that has to push the slide the rest of the way into battery as the striker spring is being fully compressed.

Oldfart's diagnosis is spot-on. Now the question is: why was the slide slightly out of battery when the trigger was pulled?

Time for the "plonk" test. Remove the barrel, hold it vertically and see if those Speer 147gr. cartridges drop freely into the chamber and fall out by gravity when the barrel is inverted.

Thanks. I'm hoping that's what it was. It's a bit of a letdown.

I'll try that test to see if the ammo falls out easily.

With that being said, I also noticed I could slightly see the bullet through the extractor mouth when it was chambered. Is that normal?

Yes, that's normal.

I had the exact same thing happen with my Q5 a couple of times during IDPA matches. A fellow shooter took the gun, racked the slide, made sure it was fully closed and then gave a good whack to the side of the gun and that caused the striker to fall. The gun went back to Walther and they replaced the whole fire control system. From reading the forums, I'm far from the only one that's had this problem. It's been perfect since they fixed it.

Did it start happening more frequently with you or was it just a few times? I feel I should see how it goes for the next couple hundred rounds and see if it happens again. I live in NYC and I would need written authorization to send the pistol out for repair (barf).

I didn't let it get beyond a few times. When he hit the side of the gun and the striker fell, I was DQ'd from the match with an unsafe gun. Send it in.

Not talking about 'dead triggers'. Talking about a failure to return to battery....a pretty common problem, which can be induced by: 1) weak ammo, 2) Limp Wrist, 3) tight gun/springs, needing a breakin, etc. There are other things that could be contributing to this problem, but I'd rate no. 2 above as the most common.

I bought my daughter a brand new P99C. Went to the range....she had a 'click no bang'....I took the pistol fired 10 rounds and it ran perfectly. Handed it back to her and she'd fire a couple and had a 'click no bang'. I began to watch her a little closer, I specifically would look at the slide to see if it had returned fully to battery after each shot and sho nuff, I saw her have another 'click no bang'. She'd pulled the trigger with the slide about 1/8" out of battery.

The cause was limp wristing. Worked great in my hands, was hit or miss in her hands. I had her work on her grip, but I also replaced the extractor spring in her 9mm with a spring from a 40 (the 40 spring is a little lighter. This absolutely fixed the problem she was having. Many boxes of ammo later, I swapped the original spring back in....gun runs perfectly.

I modified a +2 baseplate to work with her P99C, this not only adds 2 rounds for a total of 12, but more importantly added some 'grip area' to allow her to get a better grip on the gun. The +2 baseplate changes the whole dynamic of that little grip.



Here's a link to some post in reference to 'failure to return to battery'. https://www.google.com/search?sxsrf=ACYBGNSCU4_vLsxpn25dCXkuQz5hu2SBsw:1579444093293&ei=fWckXvbPEZOxtAbftrmADQ&q=PPQ+Failure+to+return+to+battery+site:waltherforums.com&oq=PPQ+Failure+to+return+to+battery+site:waltherforums.com&gs_l=psy-ab.3...26545.27440..29356...2.0..0.90.501.6......0....1..gws-wiz.OR1is4WgGkI&ved=0ahUKEwi2gv7g74_nAhWTGM0KHV9bDtAQ4dUDCAs&uact=5

From the sound of the original post I think fart is right. The problem was cause by the weapon being slightly out of battery.

I just got back from the range. I put 140 rounds without issues.

I had the habit of helping the slide cycle forward on a new magazine but today I made sure to just snap it back and release. Much better.

You just found the likely cause of the out of battery issue tsouzee

Fart nailed it!!!!

I might be explaining this wrong, but I do think the PPQ is more susceptible to this than other guns. Why? Because the firing pin is fully cocked. So the firing pin and the recoil spring are working against each other. This makes the trigger awesome but can create failure to get into battery.

If it becomes an issue then most likely the recoil spring is getting weak and needs a refresh. Ask me how I know 🙂

It's been several years since I posted here but out of curiosity I came to the PPQ section of the forum and it sounds like the failure to fire / OOB condition is still something lingering, as this post was on the front page. All in all, a bit disappointing that it is still happening in isolated cases.

Back when I had my PPQ, I dealt with a similar problem. My research led me to believe (read: my opinion) that the extractor tension, combined w/ other factors (grip strength / style), etc., could create the conditions that would cause the slide to hang up out of battery. It was obvious during slow hand manipulations, but were a clue to what could be going on during live fire, especially with a looser grip that interferes with the recoil impulse.

Some on the forum disagreed and told me I was wrong. Which is just fine. That is their opinion and they are absolutely entitled to it. It was my PPQ that was malfunctioning, not theirs. I still stand by my opinion, because after testing I knew that my my OOB condition was 100% because the case rim was not able to overcome the tension of the extractor ridge. Now, whether this was the fault of the extractor, extractor spring, or something else, who knows. As Imaoldfart has said prior (and I agree with), all the springs in semi auto pistols are a 'family' that create a working relationship together. Introduce a recoil spring that is too light, and it may not have the force to overcome the tension holding cartridges in the magazine. One too heavy, and you may get short stroking, leading to other stoppages.

It could be that the PPQ rides the edge of that working relationship a little closer that other designs. Then add in dirt, a tiring grip, whatever, and now things are pushed over the edge.

I've moved on from the PPQ, but still admire its design. I thought it had a great trigger, and was a very precise feeling handgun. Extremely accurate, and well made. Were I still to have it, I would either reduce the tension of the extractor spring, or give a very slight deburring to the underside of the extractor claw area that contacts the edge of the case rim, as see if that made a difference.

To the OP, good luck in getting things sorted out. This is a great supportive place and I'm confident that Walther will support you should you require their attention to your pistol.
