Who else thinks that this would be great in a double-action revolver?
Ruger could make one without too much trouble given the tooling they already have in place for the Blackhawk in .30 Carbine.
The .30 Carbine round is about half as expensive as .357 Mag nowadays, and a 9.5" barrell like the .44 mag Super redhawk would give the .30 Carbine some reasonable velocity.
Taurus made such a double action revolver years ago, the "Raging 30"
They could make a LOT of different things without much trouble. Taking other popular models out of the production schedule to use resources for a, well, niche market model is what keeps things from being produced.
Taurus MADE... Yup, Made...past tense. If it was such a great market they'd be making them still and have the market to sustain them.
Now if it's really believe that such a model would be a big seller, how about putting up the $$$$$$ yourself and having them built? After all if the market's there.
