Developed in response to operator demand, this tactical thigh version of the popular SERPA Technology Retention Holster allows you to have a tactical holster that offers unequaled speed and comfort, with the security of Blackhawk's patented SERPA locking system. The SERPA holster allows a rapid draw when the pistol is needed and locks securely upon reholstering. Nothing to strap, snap or rotate, it's automatic.
