The Colt Revolver is a type of firearm that uses a rotating cylinder to hold multiple rounds of ammunition. Invented by Samuel Colt in the early 19th century, it revolutionized personal firearms by allowing users to fire several shots without reloading. The design became popular for its reliability and ease of use. The most famous model, the Colt Single Action Army, was introduced in 1873 and became a symbol of the American West. Colt revolvers have been used by military, law enforcement, and civilians, and they remain iconic in popular culture, often featured in movies and literature.
