The Kimber target was starting to get some all over the place groups from my go 2 reloads that produce tight groups.
The KimTen was shooting far left and target looked like someone put a load of buckshot into it from far away.
I noticed that the rear adjustable sight was loose as a goose and had a rearward Groove and split from recoil....just junk sights...
so i ordered some non-adjustable Heinie 356p sights, hope these do the trick......

I've had a STSII in .38 Super for a long time and zero issues with the rear sight. Just started shooting another in 10mm and no issues so far...
Looks like whoever put the sight together forgot to stake something in place...

mine has about half of the wobble on that side as yours...been debating on replacing it.
Mine is recently back from Kimber for the same thing. That and other feeding issues. Admittedly, It was flawless on the last range trip. First time ever!
Sorry for the late reply...
I put the Heinie rear sight on and its spot on, couldnt be happier!
