Charter Arms Double Dog 357/38 4.2 Ported Ss/Wood 5Rd

The Charter Arms Double Dog is a dual-cylinder revolver built for shooters who want versatility without compromise. This stainless steel revolver chambers both .357 Magnum and 9mm, letting you switch between calibers with a single crane screw washer—no gunsmith visit required. The included interchangeable cylinders give you flexibility for different shooting situations, training loads, or carry preferences, all without buying a second gun.

The 4.2-inch ported barrel is designed to manage recoil and muzzle rise, keeping shots on target faster. The porting uses stylish diamond cuts that balance function and aesthetics. Topped with adjustable sights, the Double Dog is built for precision at the range or in a defensive carry role. The ergonomic walnut grip fills your hand and works to control the magnum-class recoil, while the stainless steel construction stands up to hard use and weather.

At 24 ounces with an overall length of 8.75 inches and height of 5 inches, this large-frame revolver sits naturally in hand or holster. Both cylinders are laser-engraved with their calibers so you can instantly tell them apart. The 9mm cylinder is designed without moon clip requirements, simplifying loading and carry. You'll receive extra crane screw washers with the gun so switching between .357 and 9mm is quick and straightforward.

Whether you're a .357 Magnum purist looking to train with cheaper 9mm ammo, or you want the option to carry either caliber depending on the day, the Double Dog delivers serious capability in a compact, hardworking package.
