I wouldn't mind seeing a .45/.410 single action made by ruger
A 4- or 5- shot revolver on the Single-Six or medium-frame would make a dandy trail gun....and work a lot better than the other versions out there.
I'd really like to see a LCR in 9mm & .44Spl, too. And I want Ruger to get back in the pistol-caliber carbine game. Maybe a cross b/t their PC carbine & Beretta's CX4 carbine.....
