None that I know and the applications would be very limited. The only poeple who need to reload a SAA fast are Cowboy Action Shooters and if there were a speed loaded for it the rules would instantly be changed to disallow it. Nobody carries a SAA as a duty weapon and it is most certainly not a suggested carry for any type of CCW.
The only thing I could think of is a tube with six rounds in it. Hold the tube over the open cylinder in the vertical position and rotate six times.
That tube whould be about nine inches long and is a bad solution. Since i didnt find anything about speedloaders for SAA on the internet, im gonna try to make my version. Maybe ill ask the Cowboys for tips too...
