My wife picked me up some Meprolight sights for my Walther P99 as a bday present. Has anyone installed nightsights themselves, or should I look to a gunsmith? The front sight is easy, but I am not sure on how to remove the rear sight.
Any help would be great, thanks for your time.

Rear sight is a breeze.
Use the yellow plastic punch to press down on the plunger that is below the windage adjustment screw. Then just slide the sight out of the dovetail.
You re-use the windage screw on the new rear sight.
If your new rear sight will not slide into the dovetail, lightly sand or file the bottom of the sight until it slides without too much effort.
Its a very easy project.

Darn, that was easy!
Thanks so much NM_P99

Did you lock tight the front sight screw? Mine kept coming loose till I did.

 

[mrPickles]

I had not thought to, but that sounds like a good idea. I plan on hitting the range this weekend. If the little sucker gives me any trouble, I will stop off and pick some up.
Good call, and thanks M700Police.

i'd pick some up anyway. because if it goes, you'll be looking for the front sight. also make sure the front sight threads are really clean so that the loc-tite works. some people say to use red, but i haven't had problems using that blue loc-tite.

 

[M700Police]

I used blue as well. Worked fine.

 

[mrPickles]

Ok, sights are on (I used the blue locktight as well, it was all I could find).
Took it to the range today, WOW. Ok, I know it's not nice to use all caps, but...WOW.
If you have not yet put nightsights on your fine pistol, spend the $65 and do so now. The Meprolights are a great product, and easy to install (as I found out).
Thanks to all for your advice.

I sent two broken front sights back to them. The first time I thought I overtightened it. After breaking the second I realized the screw was bottoming out on the sight and not the slide(it was still loose). I talked to meprolight about this and they said it happened a few times but realy didn't know why. They were real nice and sent me new sights each time. I ended up filing the sight down so that the screw would not hit it.

I used blue, too. Works great. Also, I Loctite'd the rear sight down because the Trijicon version has quite a lot of play; after zeroing of course.

Out of curiosity, short of hammering at the site to break the bond is there another way to break or dissolve Loctite? In a decade or so I'm going to have to replace the sights and was hoping that there might be a solvent (mineral spirits?) that loosens the bond. Anyone know?

You should be able to get an answer at locktite.com.

Heat, about 500 degrees.

I'm not aware of any solvent that works, and I've used Loctite in some hostile environments. If Loctite tells you differently, let us know.

In any event, Loctite isn't welding. Even with red, you can often just muscle the fitting off, and it works everytime with blue. The green stuff is a different matter, you usually need impact tools or heat.

I had occasion to take something off that someone else put on and I talked with a loc tite engineer and he said that red loc tite released at 400 degrees.
