<P> 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 . They are similar in size and function to the Colt Trooper and Colt Lawman revolvers . </P> <P> 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 . </P> <P> In October 1999, Colt Manufacturing Co. announced that it was ceasing production of Python revolvers . In a 2000 follow - up letter to distributors, the company cited changing market conditions and the costs of defending lawsuits as the reasons for the discontinuation of the Python line, as well as a number of other models . The Colt Custom Gun Shop continued making a limited number of Pythons on special order until 2005, when even this limited production ceased . </P> <P> The Python was originally available in two finishes: Royal Blue and Bright Nickel . The Bright Nickel model was discontinued with the introduction of the more durable satin stainless and mirror - polished Ultimate Stainless models . The stainless steel and Royal Blue finishes were offered until 2003 by Colt on the Python "Elite" model . </P>
