The SC9 Cuff Case fits most heavy-duty cuffs, for system or belt, is available in tan or black, right or left-handed. The modular interchangeable component shoulder systems (originally known as the "Jackass Rig") were invented by Galco International in 1969. Today, we continue to offer quality and versatility by developing products that enable you to design the perfect system to suit your needs. For example, you may assemble a two-handgun rig, a half harness system, or add tie downs and cuff case to an existing system. The possibilities are endless. Order based on the hand you shoot with; a right handed shooter wears his cuff case on the left side and vice versa.
