DeSantis Black Mamba Molded Nylon Chest Holster for S&W 500 8-3/8in

The DeSantis Black Mamba holster (DeSantis part no. M40BA05Z0) is a specialty chest rig molded from black nylon for the S&W 500 revolver with an 8-3/8-inch barrel, built for a handgun too large and heavy for a conventional hip holster. It is worn across the chest with an adjustable tension device that lets the wearer set exactly how firmly the massive X-frame revolver sits in the shell. The design is fully ambidextrous, so it works equally well for right- or left-handed wearers without needing a mirrored version. DeSantis builds the Black Mamba specifically for hunters and backcountry carriers who need to keep a large-caliber revolver secure and accessible while moving through rough terrain.
