For me it is a Ruger New Model Vaquero in .45 Colt with a 4 5/8 inch barrel. It is built on the smaller Ruger frame which makes it lighter than the Super Black Hawks. It is the same size as the Colt single actions. It has that classic look and will do what ever I need a revolver to do.
I'll also give an honorable mention to my S&W M-13 which packs very nicely when spending a day in the woods.
