My Ruger Blackhawk with 38/357 & 9MM cylinders. It has Ruger early scope mount with Millet red dot sight as well as Hogue wood target grips. Currently I am using the 9MM cylinder & still shoots with good accuracy at 50-75 ft. Grips are great for my large hands & red dot sight for old eyes. I let other guys try it at indoor range, they cannot believe how much better there aim is than with iron sights or laser on their semi-autos as well as speed in getting on target.
