Colt King Cobra Review 2025 The polymer-pistol generation may dominate holsters, yet a steel-framed, six-shot revolver still wins hearts for rugged simplicity. Colt’s King Cobra—relaunched in 2019 and now updated for 2025—mixes classic snake-gun lineage with modern metallurgy, an optics-ready top-strap and a factory-tuned trigger. ArrowDefence put 1 200 rounds of .38 Special and .357 Magnum through the 3- and 4-inch models, chronographed velocities, timed reloads, and carried the snub daily for three weeks to see if the nostalgia is justified or merely heavy.
Why the Colt King Cobra review still matters in the polymer era
- Mechanical certainty A fixed barrel and manually indexed cylinder resist the limp-wrist malfunctions that plague micro-9s; a misfire means pull again.
- Ammunition flexibility Feeds powder-puff wadcutters for novice recoil or full-house 125 gr JHPs for 800 ft-lb energy—no spring swaps required.
- Legal carve-outs Some restrictive jurisdictions cap magazine capacity at 10 rds but exempt traditional revolvers.
- Training clarity Visible hammer and tactile cylinder let new shooters visualise loading and clearing steps, boosting confidence.
- Collector value Snake-series Colts appreciate; you can’t say that about many striker-fired plastics.

Recoil & control in live fire: .357 Magnum revolver test
Full-power .357 loads remind you Newton had a point: the 3″ King Cobra delivers a stout snap with noticeable muzzle rise, yet the 34 mm-wide back-strap and gently radiused grip panels distribute force without biting. Shooters under 60 kg preferred .38 +P for follow-up speed: average split times were 0.31 s (.38) vs 0.43 s (.357) across ten Bill Drills at 7 m.
Compared head-to-head with a 3″ S&W 686 Plus, the Colt’s lower bore axis and lighter frame produced 5 % more muzzle flip but 10 % less perceived palm sting, likely due to Colt’s cushioned Hogue OverMold grips.
Trigger pull & reset metrics
- Double-action 9.1 lb—but linear, with zero stacking until final 1 mm. Students maintained 6 cm groups at 10 m DA after 30 minutes.
- Single-action Crisp 3.6 lb break, 1.2 mm reset you can both feel and hear—ideal for precision shots on steel rams or small-game heads.
- Hammer spur is finely serrated; cocking with wet gloves stayed positive.
Carry optics & concealment: King Cobra concealed carry impressions
The 3″ variant hides surprising well in a high-ride OWB pancake; cylinder width is 37.5 mm—thicker than a P365 but slimmer than an L-frame S&W. A Dara Holsters RMRcc light-bearing scabbard carried comfortably under a cropped leather jacket.
- Optics cut on 2025 models accepts Holosun EPS Carry or Trijicon RMRcc with provided screws.
- Weight felt no heavier than a loaded Glock 19 once balanced by a quality belt.
- Draw speed averaged 1.44 s (hide garment sweep to first DA round), only 0.12 s slower than the reviewer’s appendix Glock 48.
Maintenance & durability
After 1 200 rounds, end-shake measured 0.003″ (factory 0.002″), well inside spec. Crane pivot showed no peening; forcing cone displayed light flame-cutting but less than comparable Ruger SP101 samples. Stainless finish buffed clean with CLP; DLC variant required merely microfibre wipe.
Ammo selection: +P .38 vs full-power .357
- .38 Special +P Federal 130 gr HST averaged 957 fps from the 3″, yielding 265 ft-lb—comfortable, fast follow-ups, adequate FBI gel penetration (12-14″).
- Full-power .357 Hornady 135 gr FlexLock reached 1 300 fps / 500 ft-lb from the 3″. Effective barrier penetration but flash and concussion rise dramatically indoors.
- Compromise Buffalo Bore 158 gr Tactical Low-Flash .357 produced 1 180 fps, bridging recoil and terminal ballistics.
Carry recommendation: +P .38 for urban CCW, mid-power .357 or 125 gr JHP for trail defence.
