The Colt Python was first introduced in 1955 as Colt's top-of-the-line model. The gun pictured here was made in 1962. Pythons produced from 1955 to 1969 have no letter in the serial number and are the most desirable to collectors. The Pythons from the 1955-1963 era were all hand made and hand finished (prior to CNC machining and mass assembly line production).

Pythons have a distinct appearance. A full barrel underlug, ventilated rib and adjustable sights combine to give the gun its unique look. Originally, Colt manufactured Pythons with hollow underlugs but quickly left them solid to add stabilizing barrel weight. 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. NOTE: My nickel plated gun pictured on this page is a half century old and has been used throughout the last 50 years (not stored in a safe). How much more durable are those new finishes?

The very last guns of this model were produced only through the Custom Shop by special order and are also highly prized by the collector. I enjoy swapping out the grips on the Python from time to time. It really looks like a different gun with the walnut vs. ivory. This is one of my all-time favorite guns. The action is smoother than any revolver I've ever handled. According to Colt, it was designed to shoot 2" groups at 15 yards, and it does, even 44 years later. We recently had a visitor looking for the date of manufacture (DOM) of his Colt Python with a low serial number beginning with the KT prefix. He called Colt at 1-800-962-COLT and they informed him that the DOM was 1991. Thanks Ken, for letting us know!

According to the Colt Python Serial Number Table here, production of the Python peaked in 1981 (the highest production year). Colt produced more guns in that one year than the first ten years combined! However, 1978 is a "question mark" due to missing information surrounding guns with serial numbers that have the "N" Suffix. If more than 9,900 Pythons were produced with the "N" Suffix, 1978 would be the highest production year.

At any rate, the five year period from 1977 through 1981 appears to be the peak demand period (Life Cycle Peak) or "golden years" of production for the Colt Python. After 1981 production numbers fall off rapidly, culminating with the gun eventually being produced by the Colt Custom Shop to order only, up until production ceased altogether.

Some very lucky person out there owns the very last Python produced by Colt. I suspect the value of that gun to a collector would be very high. However, as long as Colt remains in business the remote possibility exists that they might produce another Python, thus de-throning the "last produced Python", a proposition that could never threaten the "first Python produced".

Comments and feedback welcome ...

Toward the end of 1969 the letter "E" was added as a prefix to the serial number. In 1975 the letter "E" was moved to the end of the number, becoming a suffix. In 1978 and later other letters were used.
