State law prohibits individuals from carrying or wearing a dangerous weapon of any kind (including knives, switchblades, stars, and nunchakus) concealed on or about his or her person (MD Criminal Law Code Sec. 4-101).
The owner of a business or property may carry a concealed handgun within the confines of the business establishment during the course of employment. The owner may designate a supervisory employee who is licensed to carry a gun to carry a concealed gun in the facility while the owner is absent from the facility (MD Criminal Law Code Sec. 4-203). A person may not transport or store a handgun, whether concealed or in the open, in any parking lot used by the public or on school property unless the person is a law enforcement officer or member of the active-duty armed forces.
