This is one of those "push-you-pull-me" situations. People don't demand that information, so dealers don't supply it. People don't demand it because they don't see it and don't realize how much better gun shopping is when you really know what you are looking at. Weight, balance, drop, LOP, and pitch are easy. Cast, MOI, barrel wall thickness, bore diameter, and choke constrictions take a little more doing.
