The Colt Python is a .357 Magnum caliber revolver formerly manufactured by Colt’s Manufacturing Company of Hartford, Connecticut. It was first introduced in 1955, the same year as Smith & Wesson’s M29 .44 Magnum. Now discontinued, the Colt Python was intended for the premium revolver market segment.
The Colt Python is a double action handgun chambered for the .357 Magnum cartridge, built on Colt’s large I-frame. Pythons have a reputation for accuracy, smooth trigger pull, and a tight cylinder lock-up.
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.[As a result, it features precision adjustable sights, a smooth trigger, solid construction, and extra metal. Pythons have a distinct appearance due to a full barrel underlug, ventilated rib and adjustable sights Colt originally manufactured Pythons with hollow underlugs but left them solid to work as a stabilizing barrel weight. When the revolver is at full cock, just as the trigger is pressed, the cylinder locks up for the duration of the hammer strike. Other revolvers have a hint of looseness even at full-cock. The gap between the cylinder and forcing cone is very tight, further aiding accuracy and velocity.From the 1970s each Python revolver was boresighted at the factory with a laser; the first mass-produced revolver for which this was done.
In October 1999, Colt Manufacturing Co. announced that it was ceasing production of Python revolvers. The Colt Custom Gun Shop continued making a limited number of Pythons on special order until 2005, when even this limited production ceased.
