The Thompson Center Contender 357 Magnum barrel is a versatile replacement or additional barrel for your single-shot pistol platform. At 10 inches long and chambered in .357 Mag, this barrel gives you the ability to shoot both .357 Magnum and .38 Special rounds—a practical combination for handgun hunters, target shooters, and sportsmen who want flexibility in one firearm. The chromoly steel construction is built to handle repeated shooting, and the adjustable sights let you dial in accuracy for your specific load and distance.
If you already own a Contender frame, adding a fresh barrel in a new caliber is one of the smartest ways to expand your gun's capabilities without buying an entirely new pistol. The 1-in-14 twist rate is optimized for .357 Magnum ballistics, and the drilled and tapped receiver means you can mount optics if you want to stretch your effective range. Whether you're hunting medium game, working steel at distance, or just exploring what your Contender can do, this barrel delivers the durability and accuracy Thompson Center is known for.
The blued finish protects against corrosion and fits the classic, no-nonsense aesthetic of the Contender line. This is a straightforward, proven platform—no gimmicks, just a solid barrel that lets you do the shooting.
