In September, 1981 I was at the NRA National Police Revolver Championships in Des Moines, Iowa. Many of the shooters in the Distinguished Matches were using tuned Colt Pythons. S&W was introducing their new competing model to the Python, the 586 Distinguished Magnum. Myself and team members just had to have this new gun and orders were placed. In February, 1982 we received our guns, all with AAA series serial numbers. Mine has the high post front sight that allows a neck hold on the B27 target at the 50 yard position. It took a few years to compile the required 30 points, but I finally received my Police Distinguished badge. This gun has an unbelievable smooth double action.
