In early 1999, ARDEC awarded the M1014 Joint Service Combat Shotgun contract to Heckler & Koch, U.S. subsidiary for importation of the Benelli M4 Combat Shotgun. The first units (count of 20,000) were delivered to the United States Marine Corps in 1999. During testing, the prototype was named XM1014, but after adoption, the "X" was dropped, and the weapon was officially designated the M1014.[2]
