Hello all, I recently purchased a Holland QD muzzle brake for my Ruger 480 SRH. My question is, does anybody know if the barrel on this revolver is removable? I also am planning on shortening the barrel from 9 1/2" to 6 1/2" to make it more manageable. I have a friend who is a machinist that has offered to help me with the installation. As every one knows, money is tight all around. But I do wish to do it right. I would appreciate any help on this project. You can email me direct at: [email protected] Thanks.
