I've had better luck with Rugers, personally. They may need some trigger work, but they are built like tanks, and with a cartridge like the 454, that's a good thing. Taurus, for me has been hit or miss. They are guaranteed, and quality has improved recently over the older ones. I'm thinking of a .460 S&W, that way I can shoot .460, 454, and 45 LC in the same gun. They are more expensive than either the Ruger or Taurus, but you probably knew that. Anyway, if it were me, I would choose the Ruger.
