My 10b Aya is a Matador. 3-1/2" chambers, blued frame and tight, tight, tight. I only shoot 20-25 shots per year throught it though. Mine has the gold lion under the name and some of the finest checkering I've seen on any gun. The barrels also have a bevel like none I've ever seen. How do you tell if it's a "lightweight 10 Aya"?
