I don't know if the market would support a "41 Special" but it would make sense. In my opinion it would be a better seller than a new "40 special" and easier to make because the shell would be identical to the existing 41 mag in every way except length.
In larger and heavier guns there is nothing wrong with the 41 magnum. I have always loved the old M-58 S&W revolver, but it's not made anymore.
Remington made the "M&P Load" for years and it was a very good idea for those that wanted less than full power.
The 41 is an excellent round. It never got as popular as the 44 and the 45s, but it does have a lot of merit.
