...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 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
