I've got a small issue with my 422 with the target sights. The adjustable rear sight rail is held in place with one small screw. I've tried everything to remove that small screw but it won't budge one inch. It must be held there with lock tight or something similar. Any suggesting on how to get it loose with stripping the screw?

Hmmm.... Maybe I can put a soldering iron on the screw to heat it up. Do you think that would do the trick?

Try your wife's hair dryer or a heat gun. (Get her permission first or make sure she is not at home!) Less chance of messing up your metal by touching it with a soldering iron. Make sure anything plastic/meltable is removed from the gun before you start.

It may be a silly question, but do you need to remove the rear sight assembly? The 422 series is somewhat infamous for launching the rear sight when the tiny screw works loose, which may be why a previous owner put the thread locker on it

I think if you inspect further, the rear sight assembly is also held in place by a rivet in the front forward part of the assembly. The rear screw is for vertical adjustment only. If you remove the assembly the rivet will have to be removed necessitating reinstalltion at the factory.
I don’t believe they work on this model or stock parts any longer. Would advise against removal.

I inspected the rear sight assembly on my 422 and couldn't see any rivet. All that's visible is the large rear vertical adjustment screw as well as the small rear sight rail retainer screw.

Well on my 622 there is the rear sight adjustment screw a small retaining screw towards the front of the assembly and about an1/8 inch in front of that is the rivet I mentioned.
The reason I know this is that I purchased this gun without a rear sight assembly. I inquired the factory and was told that it was also held in place by that rivet. If you look closely you should see the small round head in the location I spoke of.
I sent it in and they replaced the slide as no rear sight assembly was available. I don’t think there were two different rear sight assemblies but I could be mistaken.
I don't know about the 622 but my 422 doesn't have a rivet on the slide. However with a bit of brute force, I was eventually able to get the screw out. I did scrape the top of the screw, nothing that a little touch up blueing couldn't repair.

There were 2 variations of the sight attachment, AFAIK, one has the rivet and screw, the other just has the screw. I suspect the rivet was an "upgrade" for the early models due to the screw coming loose.

I can see that considering the screw is such a tiny one on my 6" model. Interesting to note that my 4.5" model 422 has a much more robust screw and was easy to remove.

Still wondering why you wanted to remove it?
Well the answer is quite simple. I'm one of those who likes to take his pistols apart right down to the last screw. I posted online here the complete disassembly/reassembly of the Model 52 as I hadn't seen any previous posts anywhere on how to do it. I tackled the job myself without any help whatsoever. Once you've done it, you'll understand how it functions and what role each part plays in the overall picture. It's quite the learning experience and well worth doing.

Taking the leaf off is a bit excessive though.
And to follow your line of thinking, are you also going to take the sight blade out as well? There is a lot to learn there...
Obviously not but thank you anyways for your negative contribution.

Just trying to illustrate that there was little, if anything to learn from removing the sight leaf. You perceive it as negative, that is your issue, it was a statement with foundation. Notice someone else asked why you were doing it? Wasn't that negative as well in your perspective?
And as I stated, there IS a LOT to learn from removing the sight blade, way more than just removing a screw. Make sure you get the parts that have to be destroyed before you do though...
Thank you for your response. As an owner of a model 41, I know about the issue when taking the rear sight assembly apart. In my situation the rear sight blade had to be replaced which necessitated the purchase of the windage screw and nut as they are basically damaged when removed.

Thanks a lot Summ. Give the man a snarky answer and then throw me under the bus! lol
I'll remember this. Kidcom, I totally get the idea of complete disassembly for an intimate get to know you. You are more OCD than me with removing the sight in this particular case. But I totally get scratching an itch. Best of luck and hope you'll update.

murphydog beat you to it slide, he asked first...
I thought pointing out several people asked would have been snarky. LOL
I was trying to make it through 2018 without being snarky, I didn't make it long...
