The SC9 Heavy Duty Cuff Case for Shoulder System or Gun Belt by Galco are designed to fit most heavy duty handcuffs for your shoulder system or holster belt.
Per Galco: 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.
