I have the fixed sight version of this pistol. I’m looking for night sights for it. I prefer the Trijicon HD’s with the orange ring, but the Trijicon PPQ sight doesn’t work on the SF. Trijicon’s sights for the PPS seem to work from what I’ve read online, but they are out of stock everywhere. It looks like the Truglo tritium pro for the PPQ might work, but reviews are mixed. Does anyone have any experience with these sights on a Q4 SF? Any issues with the install or change in POA/POI? Reviews and photos are appreciated. Thank you!

I buy the XS night sights about 67 bucks. Work great on all of mine. Blacked out rear, orange front surrounding a tritium vial. Since it’s a Glock cut it’s pretty simple.

I know Walther went with a Glock sight cut for the PDP, but is it the same for the PPQ slide?

The PPQ uses the P99 rear sight setup, which allows rear sight changes without the use of a sight pusher . The PPQ front sight is very similar to the Glock front sight but there are some dimensional differences which make Glock front sights incompatible with the PPQ.

The PPQ sights are the easiest sights to change and I wish the Q4 SF had that ability. I’m not sure why Walther changed it on the Q4 SF. The Q4 SF lacks the hole in the slide the PPQ has for the spring loaded plunger that engages the square windage adjustment screw in the rear sight.

Sorry I thought the Q4 slide was interchangeable including sights with the PDP SF.

Here's some good info........

I read that thread before posting here. It’s where I found out the PPS sights will work. Those are out of stock so I was hoping someone on the forum had experience with other brands. Thank you all for the input.
