What they said. I made a very realistic set of low sights for my offhand rifle initially, under 1/8" high and silver. They worked well in the woods on a woodswalk, extremely flat shooting and visible. On the range in a match, I could get maybe five shots before the heat waves from barrel ruined sight picture and the silver was often too bright. So, in my simple way, I think the original sights worked great for their purpose, but may not be a good choice for your application! Use what you have to...
