The Blackhawk in .30 Carbine is a unique chambering that adapts the M1 Carbine's rimless rifle cartridge for use in a revolver via full-moon clips. The 7.5-inch barrel is necessary to extract reasonable performance from the bottleneck rifle cartridge. The substantial muzzle blast and fireball from burning powder outside the barrel makes this configuration a memorable shooting experience. A unique solution for shooters with surplus .30 Carbine ammunition.
