Back in the eighties when I considered buying a Red Label 12 gauge and a brute at that, weighing in at over a whooping 8lbs!!!!, I read an article which said that Ruger was going to trim some fat off the Red Labels. As the models got leaner the wood would improve along with the fit and finish, the model designations would be Gold, Blue and the top of the line o/u would be the Black Label. Where the hell this side by side came from beats the heck out of me!!!
All the best
