Does anyone know the history behind the three dot contrast sights? Were they first developed based on tritium night sights and
then gun manufacturers put painted dots on their pistols to mimic the sight picture? The earliest that I recall
were on S&W semi-autos. They may predate night sights.
Was there a military or LE study that showed three dots to be superior to Von Stavenhagen (bar/dot)
or Glock's sights?
I found this article regarding Von Stavenhagen sights.
