What would be a good way to spend, say, $400.00 on a Ruger New Model Vaquero in .357 Magnum with emphasis on accuracy and shootability? The uses it will be put to include exhibition-type shooting and Cowboy Action. And although this last may seem rather silly, I'm really looking for something to set it apart, give it a uniqueness from the standard Vaquero (maybe a brass grip frame?). Any suggestions?
