Non-fluted cylinder for Ruger Security Six

alienmisprint

Does anyone know if there are any companies that manufacture aftermarket cylinders for Ruger revolvers? I have always thought non-fluted cylinders on revolvers were dead sexy, and I think I'd like to put one on my Security Six. The gun really serves no purpose other than fun shooting at the range, but I have an infatuation with .357 magnums. Due to that, I'd like a nice one. I think that instead of just saving up and buying a S&W, I wouldn't mind tricking out my Security Six.
