The Colt King Cobra Has Made a Royal Return The Colt King Cobra double action revolver has made a return to the marketplace with rave reviews from firearms experts, enthusiasts and Colt fans alike. The return brings with it a powerful double action revolver chambered in 357 Magnum, equipped with a short 2″ barrel. The 6 round capacity cylinder is what you would expect in a revolver of this size and the frame/cylinder are made from high quality steel with a matte bushed finish. This particular model features a hogue rubber overmolded grip which is comfortable and makes the pistol extremely easy to shoot. As these are Colt King Cobra firearms they tend not to last, do yourself a favor and pull the trigger on the purchase, pun intended.
