That is crazy heavy for a stock Redondo - about a 0.7 ounce difference. When I got mine, they were both correct on weight - 12.1 oz strung - spec was 12.06. My scale was only accurate to the nearest 0.1 oz. I think that most of the folks I knew with Redondos had the same experience.
Probably plays nice at that weight though.
