Lock, stock, and barrel
Lock, stock, and barrel is a merism (figure of speech) used predominantly in the United Kingdom and North America, meaning 'all', 'total', 'everything'. The effective portions of a gun (or more specifically a rifle) are the lock (used to hold ready the sparking mechanism); the stock (the portion held), and the barrel (the aiming guide and conveyor for the explosive-driven ball). Collectively they are the weapon, therefore, everything.
The term was first recorded in the letters of Sir Walter Scott in 1817, in the line "Like the High-landman's gun, she wants stock, lock, and barrel, to put her into repair." It is, however, thought that this term evolved into a popular saying some years before in England.
