Handgun holster devices are provided that allow a user to securely, comfortably and safely carry a handgun on their person. The holster may be integral with a support band configured to be worn on a body part of a user. The holster and support band may each be made from one or more flexible materials such that the device is lightweight, unobtrusive and comfortable to carry in a concealed manner. The holster includes a trigger guard that is sized, shaped and positioned to substantially cover the trigger of a holstered handgun, thereby preventing a user from inadvertently discharging the weapon.
