Being that my name is being tossed out a lot in the above post I would like to talk a little about the issue I had with the Walther Q5 SF and the development of the new stronger extractor spring that some of you have used. When I received my first Q5 SF early last year I was having many failures to “extract”, this is different than failure to eject and will likely look like the spent case is left partly in the chamber and the next round it stuck behind it. The only good way to clear this jam is to drop the Mag and to then re-battery the empty case and manually eject it by hand. I personally fought this issue for months until I came to a solution for the issue. I now own a Q5 SF Pro, Q5 SF and a Q4 SF. Both the Pro and regular SF have had this issue. I can make the issue worst by increasing the PF of the load but could not totally eliminate it by decreasing the load. It mostly happened with 9 rounds in the Mag and hardly with just a few rounds. It seems to be more pronounced the harder I held my gun. I also seemed to be more related to some of the range cases I ran as I hand load and have a little of everything. So being an engineer I dove deep into this issue and came to the conclusion that there are many factors that could cause this issue and it is not just one single thing that would get me out but at the time I was getting very frustrated and started a deep dive. First question, why was it never my Q5 polymer and just the steel frame guns. Started to look at differences between the two but for extraction there was little difference and all the parts measured and looked exactly the same under my analysis. In fact, the only difference I could really put my finger on was the weight of the gun, the steel frame was considerably heavier than the polymer Q5. I have also played a lot with the Spring-co recoil system but at the time the issue was just as bad between the stock spring and the Spring-Co recoil system using three different buffer springs. So, my conclusion was that the heavy gun did not recoil as much causing the extractor to pull from the case at the point of firing. This made sense as I could make the issue increase by increasing PF on loads, some of the range cases seemed to fail more often than others and that it mostly happened with a full magazine of rounds, i.e. gun at it very heaviest. Now with all this going on you are talking many different interactions taking place and the statistical probability that we are looking a multiple cause and effects interactions. So, I had to really make a change to eliminate this issue. Can’t change the weight of the gun, really didn’t want to rely on a particular brand of loads, as I reload and don’t want to sort and separate. So, the only two options left was the extractor spring force and the extractor design. Oh, this assumed I had already accepted the fact that lower PF was better and my go to load now is a !47 gr RN FMJ with 3.5 gr of N321 powder and I run the length 1.130 as the gun seems to love this, shoots very soft. Over a time of 5 months I played a lot with spring designs and come up with the one now in my guns. That one change, with the lower PF loads, eliminated my issue 100%. I can’t remember the last time I had an FTE on any of my steel guns as the first thing I do is replace the extractor spring. I also moved back to the original stock recoil spring in my guns. So, I run the lower PF loads, range case, N321 powder at 3.5 gr and 147 gr RN FMJ Everglade bullets set at a length of 1.130. The new strong extractor spring and original stock Walther recoil spring. Haven’t seen any issues for over a year now. Please remember that you are talking so many interactions on this issue that the solution could be one change or combination of change. You can also file your extractor hook if you want but be careful with that one. Good luck with your issues as I was just about to the point of tossing my Q5 SF in the river, but I love them all now, as I do all my guns and smile every time, I look at them. Very Kind Regards, Keith White Keithwhite100@gmail.com

I just purchased a PPQ 22LR a few weeks back and have spent some time shooting it and working on it. Here are my thoughts regarding this gun.The gun is very light in hand weighing in at a little over 19 oz., now being I have all the PPQ 5 SF PPQ and PPQ 4 SF guns this is very light in hand and feels a little like a toy. The look and grip of the gun feels almost exactly as my PPQ 5 polymer and fits my small hand nicely. There is no interchangeable back strap for sizing so you get what I consider a PPQ 5 medium grip with similar texture.The trigger does not feel like a PPQ at all and the gun I received had serious issue with a pull weight of around 6 plus lbs and a serious snag point in the pull. Being the type of person who loves working on guns as much as shooting them I promptly dissembled this gun into all it parts to determine what was goin on. I spend quite a bit of time polishing up much of the trigger bar and a lot of time at the interface between the trigger bar and internal safety lift pin Part #11 in digram below. I found this design to be marginal at best as the angle is so sharp it's almost impossible to get the flat pin to go up towards the slide via trigger bar smoothly. I was able to get it to a point I was happy with and moved to other issues. The next point of issue was the interface and the small extruding pin on the sear where it interfaced with the trigger bar, again a lot of polishing was required to remove any snag points. One additional part I spent time with the stone and polish was the firing pin safety part #29, same as the others rough and caused drag during the pull. After all this work the pull weight was then around 4.8 lbs which is about what is advertised by Walther as pull weight of 2,200 grams. So, pull weight as avertized but only after a lot of work by me to get there. Now, if you wanted to go lower in trigger pull weight you could reduce the hammer main spring and maybe reduce the striker spring so the function is good but shear is reduced but I had no matching springs in my supply to try this out and determined the outcome was not worth any additional cost at this time. The slide worked very well on the gun and no other issues were noted in this gun. I took the gun to range and put 150 round through it with zero issues, it was really fun to shoot and dead accurate, I was very surprised as I was more accurate with this gun then my Q5 SF Pro. at 50 feet I put 6 out of ten in a two inch group and three other within 3 inch and one pulled at 5 inches. I also have a Walther P22 but I think this gun is more fun to shoot and after my work functioned great. I was shooting CCI Lead Flat Nose 40 grain ammo. I normally shoot FMJ but this is all I could find during the great 2020 ammo shortage. I didn't really like the rear sight on this gun and though the notch was to wide for the front sight. So being I have several SF rear sights in the box being replaced with optics I have now installed the SF rear manual sight on this gun. Now you would think the Engineers would make the dovetail the same on this 22LR as the SF or Q5 but hell no, the slot was .010 inch smaller so I had to use a tiny 45deg file to modify this sight to fit the slide. It fits great now and I've ordered a .100 Walther Q5 front optic at .180 height and will install when it arrives. I think after this I will stop fooling around with this gun and just enjoy shooting it.Overall, I'm very happy with my purchase now and will rotate this gun to the range for the fun factor from time to time. The feel of the grip is just like the Q5 and I had no issue reaching the trigger with my small. hands. This would be a great gun for the wife that hates a heavy gun with recoil as this little tiger had neigher.keithwhite100

Did you receive them yet?

Looks interesting, is it plastic, metal or some other material? Sort of growing on me.

Does any person know if this trigger is any better than the Overwatch Protection for the Walther SF Q5 models?

I think any sort will work, I had cut some holes in a plastic project box for my loading press and used this material as it was about the right thickness and easy to shape. After I had the proper width and height (cut out using my little project scroll saw) measured the gap between the trigger bar and back stop just as the sheer broke, I then sanded the piece down to that target. Had to make one or two more sanding adjustments rubbing the piece on emery paper to get the exact thickness I was looking for and pushed it in. I have two guns with the mod and it works just perfect.

It's a low density plastic that can be shaped and sanded. Get a piece that a little thicker than the gap between the trigger bar and back wall. Then cut the width slightly wider than the placement space and force it into the slot. I have never had any of mine to fall out. It might take a couple to fit tries to get the width and thickness exactly like you want it. Good Luck.

I think you're right now that I think about it some more, was lead free as you stated.

I modifies all my guns by placing a formed plastic tab that is forced into the slot behind the trigger bar. I sand it down to the point the gun fires without interference and has almost instance reset. See attached picture. I have fired thousands of rounds with this fix and experienced no issues.

That would be the US Army that created some sort of dumb standard to reduce smoke.

0403201247.pdfOverwatch Precision trigger upgrade for Walther Q5 SF (Review by Keith White, keithwhite100@gmail.com) I’ve been sitting here at the house for the past 4 weeks with nothing to do so I decided to spend some money on my gun and purchase the Overwatch Precision Trigger for my Walther Q5 SF. The range is closed and I’ve loaded a crap load of target 9mm rounds and upgraded my press with every bell and whimsical doodad you can think of so why not give this trigger a try. I’ve been waiting for the Apex trigger upgrade and have given up on that and came across this company just the other day. Seemed like a nice trigger but I could not find anyone who was willing to purchase one and do a review, it is not cheap but more on this later. Ordered last week and it came in about 5 or 6 days, which was surprising due to the virus crap going on. Nice simple package and quality looked nice. It’s an all metal trigger and seemed to be very well made. So, I proceeded to install it in my gun. I also got two trigger springs a green and red one. A slightly below factory and one that lowered pull weight to about 3.5 lbs. I did not order this package but got it anyway and due to the fact, I run a different spring they just go into the spring bin for repurposing. My Walther has been modified in every way possible and is has a trigger as good and crisp as any 1911 or trigger job around. I run my own springs which produce a 2.5 lb. pull and have modified the shear so creep is almost nothing and 1mm reset. As you can see in the pictures, I modified the Walther trigger to the same specifications as the one sold in Germany and can be adjusted. The only issue with this is the trigger safety did no function, don’t know if the Walther upgrade has trigger safety but the Europeans seem to get away with this but not in the US. The new OW trigger fit perfectly in my gun, perfectly (not any adjustments required at all). I’ve played with a lot of Walther triggers and seem to always have to tweak them a little to eliminate any possible friction, not required with the OW upgrade. The trigger was also nicely polished up and very smooth unlike other purchased trigger upgrades. I did notice that the friction dimple pressed into the trigger bar on the Walther trigger had been ground off of the OW trigger, you can see this in the pictures, it was not an issue. Other than the shape of the OW trigger there seemed to be little to no difference between the two. The OW trigger is assembled with a tiny roll pin so it is possible to remove the safety release and access the tiny spring in the trigger its self. Assembled the gun back and gave it a few pulls, nice. However, I noticed due to the extremely light trigger spring in my gun the spring in the trigger safety was almost to strong and could lock up the pull. I’ve had this issue before on the Walther trigger and with the trigger bar springs shipped with the OW trigger, I don’t think this would be an issue. To fix this issue I dissembled the OW trigger and removed the tiny internal spring, looked for a replacement in my supply but no luck so proceeded to cut about 4 coils of the OW trigger spring and reassembled and placed back in my gun. Yes, it worked great now, no issues at all. Summary: I really like it; all the claims are true. I like the flat trigger and with my modified LOC grip in combination with the OW trigger it now fit my smaller hand perfectly. Anybody would be hard pressed to better this design. The only thing I would change is the internal trigger lock spring could be weaker as not to impede the pull with lower trigger bar pull springs installations. Was it worth the 200 bucks? For me, sure but I don’t cry and bitch about a few dollars. Could the price be lower, not sure as I think this unit was pre fit into a jig or gun and adjusted before being shipped to me. That takes time and money, I think that is why the price is higher than most other upgrades. It’s also all metal, I love this and the blue safety is an exact match to the Walther color. Nice job guys. Issued on 4/4/2020 0403201245a 2.pdf 0403201245b.pdf 0403201245c.pdf 0403201247.pdf 0403201253.pdf

Cool, I love a good product, sorry Apex, looks like you dropped the the ball on this opportunity. Walther, well you're just slow on the US market opportunities. I also gave up on the smaller grip and trigger. But love my gun.
