Hmmmm...
For what it’s worth, my barrel bands shift from heavy shooting with just the plain iron sights.
Maybe I can find a skilled welder (who knows not to overheat the barrel), and get him to weld a small stop of some kind on top of the barrel, so the sight could go "this far and no farther". I dunno, still thinking. But I do like the sight itself. Pretty neat.
Packing it in for the night. Have a good evening.
