About This Firearm
The Colt King Cobra is a six-shot DA/SA .357 Magnum revolver built for concealed carry and home defense. It has an MSRP of $1,119. It fits six rounds into a 28.0 oz stainless gun with a 3-inch barrel, one round more than the five-shot Ruger SP101.
The grip is a Hogue overmolded rubber one, fitted at the factory. The action uses a transfer bar, which Colt's manual says keeps the hammer off the firing pin until the trigger is squeezed and held back, so the revolver carries with all six chambers loaded. Frame, barrel and cylinder are brushed stainless, and nothing comes fitted for an optic or a light.
If you're cross-shopping, a Kimber K6s Stainless has an MSRP of $1,061, also holds six, weighs 23.0 oz over a 2-inch barrel and is double action only with a 9.5 to 11.5 lb pull. A Ruger SP101 has an MSRP of $939, holds five and weighs 26.0 oz over a 2.25-inch barrel. The Colt is the heaviest of the three at 28.0 oz, with a 3-inch barrel against the Ruger's 2.25 inches.

Strengths & Limitations
- Six rounds fit a frame that weighs 2.0 oz more than a five-shot Ruger SP101.
- The stainless is brushed and uncoated, so a scratch can be polished out.
- A rubber grip is fitted from the factory, so there is nothing to buy to soften .357 recoil in the hand.
- It is 8.0 inches long against the 6.62 inches of a Kimber K6s.
- At 28.0 oz it carries 5.0 oz more than a Kimber K6s for the same six rounds.

.357 Mag Ballistics →Frequently Asked Questions
Can a red dot be fitted?
Colt sells a King Cobra RMSc plate as an accessory, but this version is not sold as optics-ready.
What is the rifling?
One turn in 14, with a left-hand twist, which is Colt's long-standing convention.
Is this the single-action and double-action version?
Yes. Colt lists this version as the King Cobra DA/SA, so the hammer can be thumbed back for a deliberate single-action shot.
