So what is the facination with shooting the 9mm from a revolver? If you want a low power economical load shoot the .38's. As far as the self indexing once you get a feel for the gun it is not necessary and you won't even notice it. I have learned to index mine by feel and only rarely miss a chamber. Still a fine shooter regardless.
If one was really inclined I've wondered if getting set up to use a heel base bullet in the 9mm case wouldn't solve the accuracy problem. Of course you'd need a custom mold and the cartridges wouldn't work in a standard 9mm.
