Marketed as the "Semper Fi" edition, though no Semper Fi marking appears anywhere on the gun or box. A parts-cleanup release: refinished FDE Cerakote frames mated to whatever slides were on hand, mostly marked COLT RAIL GUN with black Cerakote finish, and at least one LIGHTWEIGHT GOVERNMENT MODEL observed with a blued finish. Black Cerakote small parts throughout and no U.S. or Q-code engravings on the rail.
