The Colt Python is a .357 Magnum caliber revolver manufactured by Colt’s Manufacturing Company of Hartford, Connecticut. The Colt Python was first introduced in 1955 as Colt’s top-of-the-line model and was originally intended to be a large-frame .38 Special target revolver. Pythons were available with 2.5-inch (6.4 cm), 3-inch (7.6 cm), 4-inch (10 cm), 6-inch (15 cm) and 8-inch (20 cm) barrels. The six-inch model was the most popular generally, and the 8-inch model was intended for hunting.
