I have one Ruger Redhawk in .44 Magnum. It's a Lew Horton 5.5" barrel blued. I was thinking about a second Redhawk in .45ACP/.45 Long Colt but now I see that it has a "sleeve and shroud" barrel. Not sure that I like this new feature. I know that some S&Ws have a similar set-up. I mainly wanted this for shooting .45ACP but now I'm thinking an N-frame S&W with a one piece barrel might be more to my liking. Here's a link to the Redhawk I was looking at....
