I am a S&W fan, but I do agree with you about them designing a revolver to handle these type loads. I shoot 45 Colt handloads in a Ruger Bisley for that very reason. Obviously, the new X frames will do the job (the 460 will take 45 Colt or 454 ammo) and they are impressive guns. For my use, the X Frame is too much. Something betewwn the N Frame and X Frame seems right.
