The Blackhawk SERPA Shoulder Harness allows you to convert a SERPA holster, supplied separately, into a shoulder rig. It mounts horizontally under the arm. The tapered web harness straps provide a secure and adjustable fit that delivers efficient load distribution for maximum comfort. They are also stable enough to allow quick one-handed reholstering as well as a fast and natural draw, thanks to a lower strap that anchors the harness to your belt. The off side of the harness includes a dual Picatinny rail platform, allowing you to mount compatible accessories as required to suit your mission.
