Thanks for the warning!
I saw this vid about taking off a rear sight that looks like mine:

Around 6:15 it starts disassembly of the rear sight, which was pounding on it from the left side with a non-marring hammer.
Then, finishing it off with a punch, while making sure you hold a plate down so the springs don't come flying out:
2 springs, a plate and 2 "buttons."
Another vid showed putting it back together.

begins around 1:20
All seems simple enough.
I found the right size for the screw that was a small hex key/Allen wrench.
Question: If pounding on the side of the sight moves it from right to left, is the screw that is on the top of the sight for elevation?
I assumed it was there to hold the sight in place with tension, but since it takes a hammer to pound it out, perhaps not.
In the vid, it showed the screw had been backed out to make it easier to take off the sight.
Note: I sprayed some CLP to help the screw come out, and was able to back it off.
There was some red coloration on the threads, I assume locktite, which would indicate that is is not for manipulation for elevation.
But, if locktite, I would think it would have been a battle to get the screw out, but broke free readily.
After taking the screw all the way out, I sprayed CLP down the hole and put the screw back in.
There wasn't any raising of the rear sight when backing the screw out.
When I screwed it back in it just "hits the wall" and it's done.
I didn't try to force the screw in more past "the wall" to see if that would raise the rear sight, in case it would strip and that's not its function anyway.
I will spray under the rear sight and let it sit overnight to see if that will make it easier to move the sight to the left where I want the POI to coincide with POA, since I want to bring it more to the left.
I'll worry about elevation later, I can compensate some for that anyway.
