Increasing extractor tension seemed to help me. I tried by applying a slight bend, but another suggested this is the wrong approach, as the type of metal of the extractor does not allow for that. Using a stiffer extractor spring will accomplish the same result, and is easier to replace, if needed.

I had a similar extraction jam after my "fix" of bending it a couple of thousand rounds later, am very interested in trying a stiffer spring. I don't tolerate any of those malfunctions in my competition rig. The spring switch seems to be a better solution. Thanks for sharing that.

I had theorized that the loose mag fit was interfering with extraction in some way, but would like to see how this mod does, as there is not an easy way to adjust those mag guides.
Let me know if I can help, I know your feeling when it james, it just sucks and stops you dead in your tracks.

Ok guys, I got my first malfunction with my Q5 SF during today's match.

I was trying some hand-loaded match ammo for the first time - 147 gr, ~133 power factor. I had used it for about 40 rounds when the slide didn't go into battery, I racked (with mag still in) and got a double feed. Didn't have time to see exactly what happened.

Several others at the match was using the exact same hand-loaded ammo and didn't have any problems with their pistols.

The rest of the match I used my regular 124 gr Blazer factory ammo with no problems.

It seems like the Q5 SF is indeed very picky. If a new extractor spring fixes it for me too, I want one!

If it was just one round, I wouldn't worry too much about it. I'd be more concerned about what caused the failure to feed rather than the failure to extract. It may have been a bad round of ammunition.

It would be better to hold onto the cartridge/casing if possible if this happens again.

I posted the same malfunctions others were seeing earlier. I have found as long as power factor is >135 I haven't had any additional issues. I do have to watch my mags...with Springer extension and grams followers I get a reloadable 22; 23 will fit but reloading it into a loaded chamber is a no go. With TTI extensions and the factory follower I get 21. Once gun, I just have to work on me.

So the only solution with my issue was to increase the holding force of the extractor. After detailed inspections of the claw I could see not real way to improve on the design. So my only option was to increase the extractor spring force. So after a lot of looking and testing I came up with a spring which added about 1 additional pound of force on the extractor. I tried higher but then I started to scar the case and it became harder for the extractor to engage the loading case.

Fully Ejected, Keith White
Thank you so much Keith for your test. May I ask what spring (add 1 pound) and where did you buy it? thank you again.

Any chance we can get a few side-by-side pictures of the factory and aftermarket springs?

Thanks for your R&D. But, who is Keith? And, is there a part number for that replacement spring? What was the replacement spring originally used in/for?

I'm only asking because others may be experiencing the same issue and they might want to pick up one of those springs.

It could be the information I'm seeking is buried in the previous 13 pages....idk.

"Keith" is forum member "keithwhite100". He's been posting on this thread, and has stated that he would be selling this heavier aftermarket spring to forum members here to fix this issue. He has not publicly stated where he has gotten this spring.

I put it out there earlier on this thread that I've spoken to a 99-series pistol armorer who has told me that on 99-series pistols, Walther used to advise using a P99 mag release spring as the extractor spring if there were extractor tension issues. The P99 mag release spring was heavier than the factory extractor spring years ago when he was an armorer for a local PD that issued SW99 pistols.

Has anyone with a PPQ SF compared part numbers, or tried substituting the extractor spring for the P99 or PPQ M1 mag release spring?

Thank you so much sir.
Is the ppq m2 mag release spring the same as P99/PPQ m1?

Hi, Let me introduce myself, i'm a retired technology leader that worked for Procter and Gamble for 30 years. I have designed both consumer products and high technology machines that product consumer products. My primary focus was on machine design, reliability and quality production.

I started shooting 4 years back and quickly got into reloading and shooting for fun with many different guns and platforms.

So when I purchased my new Walther SF I was somewhat disappointed that I had an issue with FTE from day one. So, I did what I've done my whole life, set out to fix the issue. I used this forum to gain experience from others thinking there would be a fast solution to the issue. Well not so, it has taken me countless hours and thousands of rounds and money to come to what I believe is the best solution to the issue my gun had. And based on this forum I was not alone.

The spring I developed to resolve this issue is not a shelf item, it's not sold by any gun manufacture and has to be special ordered in minimal order batches.

Based on my time and efforts I'm happy to sell any person a spring but I will not be publishing the specifications.

Feel free to send me an email to further discuss at [email protected]. or send me a private message. I'm offering the springs at 10 dollars each and if you order 5 or more I will sell for a reduced price. Not trying to make money but rather get back my investment at this time. I don't have a web site and don't have plans to develop one as I love my free time and retirement at this point in life.

What I can't understand is why Walther has not responded to this issue as I'm sure they read this forum. I also know there are many factors that will create this issue and most gun users will never experience a problem or if they do it's so infrequent that will just clear the issue and move on. Having a career in manufacturing I understand the complexity of standardization and difficulty of making changes to products already released into the market, however this is a serious issue and will not go away so the sooner they address this the better.

Kind regards, Keith
