Galco's original VHS™ (Vertical Holster System) was field-proven across the globe from Afghanistan to America. Thousands were used by US military personnel fighting in Iraq and Afghanistan. Countless others are in use by US and international law enforcement, being particularly popular among police helicopter pilots. The VHS 4.0 also provides an alternative for those who want the concealment of Galco's Miami Classic but prefer the traditional vertical carry style. Fully modular, optional accessories and components for the VHS 4.0 may be purchased separately.
