Bond Arms Handgun Barrel .357 Mag/.38 Spl 3.5" Matte Finish

The Bond Arms .357 Mag/.38 Spl 3.5" barrel is a practical upgrade for owners of Bond Arms derringers who want to change up their firearm's caliber capability or refresh its appearance. This matte-finish replacement barrel fits all original Bond Arms frames (except the Stinger model), letting you swap calibers on the same proven platform without buying a whole new gun. Whether you're a concealed-carry shooter looking to standardize on a more common defensive round or a collector building out a versatile two-shot handgun, this barrel delivers the quality and reliability Bond Arms is known for.

Bond Arms derringers have earned their reputation in the backup gun and deep-carry market for simplicity, durability, and no-nonsense performance. Swapping barrels is the economical way to explore different cartridges on the same frame—you get a fresh gun without the extra weight or complexity of a larger pistol. The .357 Mag/.38 Spl chambering is a classic choice for defensive work and practice, with good ballistic options across modern factory loads.

This barrel arrives with a matte finish that resists glare and plays well with holsters and carry methods. Installation is straightforward for anyone familiar with their Bond Arms derringer; if you're new to barrel swaps, Bond Arms customer service can point you toward resources. Make sure your frame is an original Bond Arms model before ordering—this barrel won't work with Stinger frames.
