Concealed carry
Concealed carry, or CCW (carrying a concealed weapon), refers to the practice of carrying a handgun or other weapon in public in a concealed or hidden manner, either on one's person or in close proximity. While most law enforcement officers carry their duty pistol in a visible holster, some officers, such as plainclothes detectives or undercover agents, carry their pistols in concealed holsters. In some countries and jurisdictions, some civilians are legally able or obliged to carry concealed handguns.
