Front sight fell out. PPQ M2 Navy

So Sunday night I pulled out the PPQ to do some dry fire practice and I couldn't pick up the front sight. Turns out it had fallen out completely. Just an oval hole in the slide was smiling back up to me.

I emailed Walther and they are going to send me a new sight. First I figured I'd make you aware of the problem. I've only had to the range about 10 times. Only once did I draw from the holster. I've never banged it or hit against anything.

Question - will this be a simple fix for me, or will I need to bring it to a gunsmith? From the manual it looks like one screw, but is there only one position? Or can something I do affect the point of aim as it came from the factory?

And here I was worried about losing the thread protector.....

No biggie Mattiooo......only thing I think of to be careful of is when you're installing the front sight, be sure the white dot is facing to the rear.

Here ya go....post #6 New Dawson Percision Sights Installed

Here's another picture, it shows the little 'wings' on the two ears that'll snap into the slot in the slide. You can push the sight in with your thumb (maybe), just make sure the sight is fully inserted and flush with the top of the slide. I sometimes pick up the slide (after inserting the sight and before inserting the screw), turn it upside down and use the slide like a hammer (well, sort of) tapping the front sight onto the top of the work bench....just a gentle tap.

Now, you can lay the sight upside down on the work bench and go about inserting the tiny set screw. If the set screw comes (separate) in the package (plastic bag) then you need to exert a little pressure as you're trying to screw the set screw in between the two ears, cuz, you're pretty much cutting threads in the plastic. If the set screw comes already screwed into the sight, you'll need to completely remove the set screw prior to inserting the sight.....but the good part is, you've already got some threads cut into the plastic, so it'll make reinsertion of the set screw a piece-0-cake. NO Loctite required...I'm not sure it works on plastic anyway.

I'm laughing at this, but I have made many similar mistakes in my lifetime.

FWIW, the stock PPQ sight is plastic. Loctite is superfluous. Only needed on metal to metal.

Same thing happened to me. Walther sent me a new sight immediately. I installed it properly and it has been good to go ever since.

Since I was curious, I looked at Loctite. This is what their FAQ said:

All Loctite Threadlockers: Metal-to-metal applications
Loctite 425 Assure: Plastic-to-plastic, plastic-to-metal applications

Here is the link to the 425: LOCTITEŽ 425? Instant Adhesive - Henkel

Mattiooo......you don't need to use loctite on the factory 'plastic' front sight. REALLY. Just replace the sight as outlined in post #2. When you screw the set screw in, screw it until the top of the screw is flush with the top (or is that bottom) of the two plastic flanges/ears on the sight. That's it.
