Two cylinders in one box is the idea behind the Blackhawk Convertible. Ruger supplies a .357 Magnum cylinder and a 9mm cylinder for the same frame, so one revolver shoots both cartridges. It has a 6.5-inch barrel, six rounds, and a black finish.

The flexibility pays off in the ammunition box. A shooter who already keeps 9mm for a pistol can run the same ammunition in the revolver, and swap to .357 Magnum or .38 Special when the job calls for it. Swapping cylinders takes only a minute with the right procedure from the manual.

The Blackhawk frame is strong and built for heavy loads, and the long barrel soaks up recoil and adds a long sight radius. The result is a handsome, steady revolver for the range, the trail, and handgun hunting where legal.

Use only ammunition in the correct cylinder, and follow the manual closely. Wipe the black finish after use and keep the action lightly oiled. Load through the gate and carry with the hammer on an empty chamber. The revolver ships to your FFL dealer, where the background check is completed before pickup.
