A shoulder holster system secures a handgun under the arm, typically supported by a harness that distributes weight across the shoulders and back. Different configurations exist, accommodating various firearm sizes and user preferences, such as vertical, horizontal, or cross-draw orientations. Choosing the correct configuration depends on factors like firearm size, body type, and intended use. For example, a detective might choose a vertical configuration concealed under a jacket, while a security professional might opt for a horizontal, open-carry setup.
Proper fit and adjustment are paramount for comfort, concealment, and quick access. Historically, shoulder holsters have been employed by law enforcement and military personnel for their ability to carry a sidearm while keeping hands free. This practicality extends to other professional fields and recreational activities where quick access to a firearm is essential while maintaining freedom of movement. Secure carry and efficient presentation of the firearm are crucial benefits, achievable through informed selection and proper adjustment of the holster system.
