Ruger Blackhawk, .30 M1 Carbine cal. single action revolver. Serial #51-06500. New Model. Very good condition. 7 1/2" barrel has an excellent bore. Nice tight action. 94% blue with some rubs and marks on the cylinder walls/edges and some light muzzle wear. Adjustable rear sights. Pac over-size checkered soft rubber grips are excellent. Includes leather Hunter belt holster in very good condition. These really snap out there and make an ideal varmint getter! When first introduced in the 1960's this chambering was considered revolutionary and very useful as there are MILLIONS of rounds of cheap M1 Carbine surplus ammo to burn up! Still real, real fun six-gun! Gunrunner West item.
