szhttm Posted July 21, 2019 Share Posted July 21, 2019 (edited) If you have run your competition ammo in your Walther Q5 and/or Q5 SF through a chrono, please list your model gun (Q5 or Q5 SF), bullet weight (115, 124, 147, etc.), average power factor, encountering any issues (none, Failure to Extract, Failure to Eject), and if you are using a factory or different recoil spring (list new weight spring weight). I hope to publish my complete results next week (I need to chrono my competition ammo). I am not asking for your load data but just the bullet weight you are using and the average power factor you determined after running the ammo through a chrono. My data Model Gun: Q5 SF Bullet Weight: 147 Power Factor: TBD Encountering Issues: None Recoil Spring: Factory As per a response I received, depending on the bullet weight you are using you may need to load to an average power factor. I'm also assuming at this time that the factory recoil system is set up to handle NATO ammunition. With your help in providing the information requested above, I think we can help isolate it down. Again, assuming at this time, I believe changing the extractor spring to Keith's new version and a lighter recoil spring (depending on your power factor) will help prevent the issues some are having with Failure to Eject and/or Failure to Extract. I also believe the Walther Q5 and Q5 SF come with really fast barrels. So if you haven't run your ammo through a chrono, I think you will be surprised at the results when you do. If I can and can figure out how to do it, I plan to insert a spreadsheet here to gather all the data received. Thank you!!!

MemphisMechanic Posted July 21, 2019 Share Posted July 21, 2019 (edited) Q5 5” PPQ M2 Two different 4” PPQs They eat factory 115s just fine. Thousands of round of it downrange. My competition guns are running a 13lb 1911 wilson flatwire spring on a custom machined guide rod. They’ve eaten 124, 135, and 147gr ammo without a hitch. I load to roughly 135pf when developing a load, so everything’s 133-137pf. I’ve never seen anyone local have issues getting a Walther to run reliably. But they do indeed have very fast barrels.

PokerNGuns Posted July 21, 2019 Share Posted July 21, 2019 (edited) Poly Q5 will eat anything with factory setup no matter bullet size and any Pf from 128-140(probably higher) in my experience. Q5 Sf on other hand needs some competition refinement. Everyone I have talked to since gun came out in January and I got mine has had some issue usually FTE. Most cases have been with reloaded ammo that “works fine” in other guns including poly Q5. My fix was a 13lb Wilson flat wire on a ZR tactical PPQ guide rod with 1/8” hole drilled in back. Running uncapatured like this may be the reason I have a slight chip on muzzle end of frame that guide rod/spring sits on so decide for your self if it’s worth it. I have had this setup since March and have run 147,135 and now 125 Blue Bullets in same PF range. Model Gun: Q5 SF Bullet Weight: 125gr BlueBullets Power Factor: 134-136 Encountering Issues: None Recoil Spring: ZR Tactical Edited July 21, 2019 by PokerNGuns Link to comment Share on other sites More sharing options...

Everyone I have talked to since gun came out in January and I got mine has had some issue usually FTE. I have yet to have any issues feeding or extracting. The gun just runs. Same with 2 friends that also have SF's.

Chrome308 Posted July 22, 2019 Share Posted July 22, 2019 (edited) Stock springs seem to work in my gun down to about 130pf, below that you need a reduced power spring. After some testing I settled on ~125pf 147gr FN loads with titegroup, which seemed to have the least subjective recoil of the various bullets and powers I tested. Model Gun: Q5 SF Bullet Weight: Precision Delta 147 FN Power Factor: 125 (tested) Encountering Issues: None Recoil Spring: SpringCo White (~13 lbs) Edited July 22, 2019 by Chrome308 Link to comment Share on other sites More sharing options...

Abflyboy Posted July 23, 2019 Share Posted July 23, 2019 Running stock RSA, tried the Walther tungsten RSA and liked the poly one better. First Q5 poly has approximately 15k through it with ZERO issues, second Q5 poly has about 1,500 rounds through it with also ZERO issues. Both are set up for Carry Optics. My load is 135 pf Accura 124 grain plated over Sport Pistol powder. I like the feel of a slightly higher pf and it shoots extremely well. This load runs in all of my competition guns and has yet to cause any problem. I also use range pickup brass and only cull steel, aluminum, or 2-piece cases. Q5 polymer Accura plated 124 gr 135 power factor (verified on multiple chrono's) No issues whatsoever Factory RSA There are also 2 PPQ 4" guns that I shoot regularly with the same load. I have not chrono'd through these guns yet but ZERO problems and all my PPQ's are factory spec. Link to comment Share on other sites More sharing options...
jdlincoln Posted July 24, 2019 Share Posted July 24, 2019 What OAL are folks running with 147gr coated? Interested since I just ordered a SF and have thousands of 147gr.coated FP's loaded @ 1.148 that make between 880 and 920 from other 5" barrels.

You will likely find that combination will need to be shortened down into the 1.090”-1.110” range in order to fit the short-chambered Walther guns. There’s a reason I had a carbide reamer made: All my Walthers will eat anything out past 1.150” now. These barrels are HARD and will destroy most chamber reamers.

I don't see an 11 listed, but I do have an assortment of regular 1911 springs ranging from 8-18 lbs. Suppose those could work too? I did order the 13# flatwire just now.
