When I first got my PPQ M2 .22, it, it was shooting high and right. The windage adjustment was straightforward with the set screw. From what I can tell, the elevation adjustment screw changes the height of the rear sight leaf. I turned the adjustment screw clockwise to lower the leaf. My issue is the adjustment range of the leaf is very small. As I continue to turn the screw clockwise it has no more effect yet continues to turn, never bottoming out. The leaf itself could go lower as I can tell by pressing it with a finger against the spring, but the screw is having no further effect. I’m attaching photos showing the maximum adjustment range on the rear sight leaf. Does that seem right? At the lowest setting, as shown in the photo, it still shoots 3-4 inches high at 20 yards.

I don't have a PPQ 22. So, I don't know exactly how the rear sight elevation adjustment works. BUT if the screw keeps turning and has NO effect, it'd seem to me that the threads may be stripped....hey, that's just a WAG.

Someone replaced their PPQ 22 rear sight with one for another pistol....may have been a M&P....can't remember. As I remember the sight fit the dovetail in the PPQ, but was a little too wide....requiring a little filing to reduce the overall width. Again, as I recall, the M&P allowed for more elevation adjustment and seemed to remedy the less than acceptable elevation adjustment problem on the PPQ 22.

OR, if I had one of these, I'd probably look at removing the rear sight, disassembling the sight and then use a file to remove some material off the top of the rear sight.....may need to make the notch a little deeper too......just a guess. But filing it down....Oh Yeah...I'd do that in a heartbeat.

Thanks again. I called Walther customer service and ended up sending my slide to the repair facility. I'll see if they can fix it up.

I wasn't filing on the gun, just on the aftermarket rear sight 😛

But I did file the pointy ends on my Kimber trigger off some. Damn they were sharp and pointy.

Yesterday I picked up a new 5" PPQ M2 .22. It also shot high. I got it down to 2" high at ten yards by bottoming out the rear sight. After looking through my packaging, I found my pistol came with two front sights. (both fiber optic versions, held in place with a very small screw!) The sight on the gun had a four printed on the bottom. The one in the case had a "5" printed on the bottom and appeared, to the naked eye, to be a higher sight. I took the 4 off the gun and put the 5 on and then had to re-zero all over. (Damn, more shooting, will this torture never end.) The higher front sight blade made a big difference.

I see this thread is several months old, I'm just hoping this is indicative that Walther has hear our comments and taken remedial action to make sure their bases are covered!

I just joined as I recently purchased a PPQ M2 5" 22LR. I was enjoying this for the first time yesterday when the rear sight literally came apart after 75 rounds. Prior to shooting I checked all screws and fittings to ensure that the test flight would be OK. Amazingly I was able to find all the pieces including the tiny elevation spring. Upon examination of the sight it is clear that this is a useless piece of junk. It literally rattles in the dovetail and the design is abominable. I am extremely disappointed. The sight is a Novak style but about 15 thou shorter than a typical Novak dove-tail opening. I have a few unused Novak sights from my STI 9mm and I will modify one to fit and hopefully find a front sight to match. Such a great gun would have been better off with a fixed rear instead of this poor excuse of an adjustable sight which does not do that very well.

In case anyone else has this sight issue (I did, as well as having the rear sight break within the first couple hundred rounds) I designed a sight that can be 3D printed. I printed it out of PLA filament and it works and looks great. You can find it on here: https://www.thingiverse.com/thing:3999234

It's a fixed sight (no height adjustment) so I upload files of a few different heights. I ended up using the second shortest (5.2) combined with the stock #4 front sight.

If you look in the Walther section of the Rimfire forum there is more information about PPQ M2 sight issues. I have posted on that site about my mods which include the installation of a Williams adjustable rear sight intended for a S&W M&P 9mm and a PPQ M2 9MM front site made by Dawson. The Dawson sight is not a perfect fit but I made it work. I needed a taller front sight to work optimally with the 5" barrel. The stock sight should work with the shorter barrel. The Williams sight is excellent. The stock Walther sights are an abomination and embarrassment to the company. Unfortunately I am unable to upload pics on this forum however images of my modified gun are on the Rimfire forum.

Hi, I have the same problem, did you fix it in the end? What did you do?
Thanks
Jrsbike pointed you in a good direction. For myself, I mounted an optic. https://www.waltherforums.com/forum/#/topics/115938

Also the problem I had with the stock sight was it shot high even with the rear sight set to the lowest position. After I put the optic on, I noticed that along with the stuff in the original case was another front sight. I thought that was just a spare but later saw it was a slightly higher front sight. Maybe you got one also if your problem is it’s still shooting high.

Well... I came here to see if anyone else had the “can’t adjust the rear sight enough” issue, and saw this. I’d seen the extra sight in the case, but didn’t realize it was a different size. Swapped the “4” for the “5” and that did the trick. Thanks for saving me a call to Walther!

I had exactly the same issue with my 5" PPQ 22. Btw, my young kids and I love this gun to death! A perfect "trainer" for my other PPQ's in 9mm that are just a little to powerful/intimidating at this point, for them to really "enjoy" shooting them - this gun, they won't put down..
Yes, the rear sight is crap, but there are work arounds, as others have said. Best being replacing the front #4 sight, with the #5 (taller) sight, that comes with the gun - thanks to David 1959"s post #8 pointing this out.
One other fix I found, was to depress the sight leaf with a small screwdriver blade with one hand, all the way down so it bottoms out, and hold it there while using the other hand and screwdriver to turn the elevation screw to a a point where it "catches" the leaf in its lowest position possible. This will not be at its lowest point, but a bit higher, yet still quite a bit lower than shown in Banditrvp's "lowest setting" photo. This position now shoots very close to zero at 7-15 yards, instesd of 2" high.
Biggest gripe, is that it's just a little difficult to get a good rear sight picture with all the different heights of the top edges your eyes have to accommodate. I just ignore the top edge of the front sight, and bury the bottom of the red dot to be tangent to the top of the leaf, and that works well - not fast by any stretch, but works.
The second pic is of the final position of the elevation screw that holds this in place - note that it will spin loosely in either direction from this point, and do nothing, but at one position, it had a little resistance I could feel, and it did hold down the leaf in its final position. It doesnt seem to move after shooting multiple outings, but using loctite is probably a good idea.

Here's a pic of my lowest position I could get my leaf to sit at, followed by a pic of the elevation screw in the position of greatest resistence - your position of the screw may not look exactly like mine did, you have to feel for it... it will not be "tight" at all, just not totally loose like it is to either side of this position. The third pic, shows my gun with a budget green laser attached that helps as a training aid - lets them see how steady their grip is, and to shoot with both eyes open. Plus it looks very cool to them, and gives them additional confidence to hit what theyre aiming at - and to better transition to the 9mm PPQ's that also have green lasers on them.
And yes, I make them train with just the sights, on every outing...actually, they're all more accurate with this than I am.. go figure.. but makes me very happy and proud of them :)
