A shoulder holster is a type of firearm holster designed to be worn over the shoulder, allowing for easy access to a handgun. It typically consists of straps that go around the shoulders and back, holding the firearm in a position under the arm. This design is popular among law enforcement and concealed carry enthusiasts because it distributes the weight of the gun evenly and keeps it hidden from view. Shoulder holsters can be made from various materials, including leather and nylon, and come in different styles to accommodate various handgun models. They are often adjustable for comfort and can be worn under a jacket or coat, making them a discreet option for carrying a firearm.
