I wouldn't be surprised to see .41 Special's on the GP100 / Ruger New Vaquero frame produced for Lipsey's. Starline is making brass and hopefully a manufacturer like Hornady could step up and produce mainstream factory ammunition. My dream factory gun from Ruger would be a Bisley Single Six in .41 Special--several custom gunsmiths will do that build, but it requires an owner who knows the gun's limitations and is willing to load accordingly. That likely is why it never will be built by Ruger.
