I have a birthday coming up soon and looking at getting a new 454. I'm considering a Ruger Bisley sbh but not sure if I want the 4 5/8" or the 6 1/2". I was thinking that the 4 5/8" would be handy for carry but I'm a little concerned about sight radius, muzzle blast, and velocity lose. I have not seen much discussion on this forum about these new Rugers, so I would appreciate any feedback you can give me. I'm also open to any discussion on the BFR's Thanks
