The Colt King Cobra is a double-action/single-action revolver chambered in .357 Magnum, also compatible with .38 Special and +P ammunition. Originally introduced in 1986, the revolver returned in 2019 as part of Colt’s modern “snake gun” revival, bridging the gap between the compact Colt Cobra and the large-frame Colt Python.
Built from solid stainless steel and featuring a full underlug barrel, transfer-bar safety, and six-round cylinder, the King Cobra delivers premium shootability with classic Colt styling. Available in 2-, 3-, 4-, and 6-inch barrel configurations, it serves multiple roles—from concealed carry to competition—making it one of the most versatile revolvers in Colt’s lineup.
When Colt announced the revival of its legendary “snake gun” line, enthusiasts knew the King Cobra had to return. First launched in 1986 as a workhorse revolver for duty and defensive use, the King Cobra quickly became known as the “Python’s practical sibling.” It combined the accuracy and aesthetics Colt was famous for with a simpler, more durable action suited for heavy use.
After production ended in the early 1990s, the King Cobra gained a cult following—commanding collector prices on the used market. In 2019, Colt officially reintroduced the King Cobra, redesigned for modern shooters while retaining its DNA: the heavy underlug barrel, six-shot cylinder, and that unmistakable Colt trigger feel.
Today’s King Cobra caters to a broad audience—law enforcement professionals, home defenders, range shooters, and revolver enthusiasts alike—by blending classic craftsmanship with updated ergonomics, modern metallurgy, and +P ammunition compatibility.
Specifications
Design & Build Quality
The Colt King Cobra stands out immediately for its robust, all-steel construction. Colt engineered this revolver with the same level of refinement found in the Python line, but with a focus on durability and everyday practicality.
Frame and Finish
Every King Cobra is built from forged stainless steel, with either a brushed or matte finish that resists fingerprints and holster wear. The machining quality is excellent—tight lockup, zero cylinder play, and an overall sense of mechanical confidence. Many owners describe it as “built like a bank vault but balanced like a sports car.”
Ergonomics
The revolver’s Hogue overmolded rubber grips provide excellent recoil absorption and control. They are comfortable for extended sessions, though some users prefer upgrading to slimmer wood grips for aesthetics or improved concealability. Colt’s enlarged trigger guard makes operation easy even with gloves—a thoughtful detail for field or duty users.
The King Cobra’s balance point sits slightly forward, due to its full underlug barrel, which aids in muzzle stability and reduces muzzle rise during rapid fire.
Controls
Colt maintains its traditional rearward-activated cylinder latch, a hallmark of Colt revolvers. The transfer-bar safety system ensures the revolver cannot fire unless the trigger is fully pressed, providing safe carry with all six chambers loaded.
The spurred hammer is easy to cock for precise single-action shots, while the double-action pull is remarkably smooth.
Variants & Model Differences
King Cobra 3” (Standard Model)
The most popular configuration for concealed carry and general use. It offers a 3-inch barrel, six-round cylinder, brass bead sight, and a balance between portability and shootability.
King Cobra Carry
A 2-inch variant with a bobbed hammer for double-action-only operation. Designed for concealed carry, it eliminates snag points while retaining the same rugged frame and +P capability.
King Cobra Target (4” and 6” Models)
Built for accuracy and range performance, the Target models include adjustable rear sights, a fiber-optic front, and Altamont checkered wood grips. The 6-inch version is particularly popular for competition and hunting applications.
King Cobra Limited Editions
Colt occasionally releases special edition models with polished finishes, engraved frames, or collector packaging.
Comparison with Similar Revolvers
-
Smith & Wesson 686: The King Cobra competes head-to-head with this model. Both are stainless .357 Magnums, but the Colt offers a slightly smoother trigger and distinctive styling.
-
Ruger GP100: The Ruger is bulkier and heavier, but nearly indestructible. The King Cobra trades a bit of overbuilt ruggedness for refinement and better balance.
-
Colt Python (Modern): The King Cobra is more affordable, lighter, and more compact—essentially a practical carry or duty companion to the Python’s luxury-grade performance.
Performance
Accuracy
The King Cobra’s fixed barrel alignment and consistent cylinder timing result in excellent accuracy. In tests, 3” models grouped within 2 inches at 15 yards with .357 Magnum, while the 4” Target version routinely produces sub-2” groups at 25 yards.
Trigger
Colt’s LL2 (Linear Leaf 2) trigger system delivers a smooth double-action pull with minimal stacking and a crisp single-action break around 4 pounds. The action is predictable and controllable, contributing to both speed and accuracy.
Recoil & Handling
While .357 Magnum rounds produce noticeable snap, the revolver’s 28–32 oz weight and Hogue grips make it manageable, even for new shooters. Most owners find it comfortable to shoot extended sessions using .38 Special or +P loads.
Reliability
As expected from a Colt revolver, reliability is top-tier. Users report flawless performance through hundreds of rounds without timing issues or misfires. Cylinder lockup is solid, and the transfer-bar mechanism ensures safe operation.
Durability
The King Cobra’s all-stainless construction resists corrosion and wear. Colt’s metallurgy and assembly quality make it capable of withstanding decades of firing without degradation in performance.

Use Case Suitability
Concealed Carry
The 2” Carry and 3” Standard models are ideal for concealed carry. Their manageable weight and rounded contours reduce printing under clothing. While slightly heavier than alloy snubs, the extra mass translates into better control and faster follow-ups.
Home Defense
Loaded with .38 Special +P hollow points, the King Cobra excels as a home-defense revolver. Its intuitive manual of arms, visible hammer, and proven reliability make it dependable for less experienced shooters as well.
Competition
The 4” and 6” Target models appeal to IDPA or revolver-division competitors. The smooth trigger and adjustable sights give shooters the precision advantage needed in timed stages.
Hunting / Outdoors
With its .357 Magnum chambering, the King Cobra makes an excellent trail companion. It’s suitable for small to medium game and as protection against predators, especially with hot magnum loads.
Recreational Shooting
Even casual shooters find joy in the King Cobra’s balance and smooth action. It’s a perfect range revolver—fun to shoot, mechanically satisfying, and a standout in any collection.
