Bond Arms Barrel Features The Bond Arms Barrel is chambered in .357 Mag and .38 Spl and measures 2.5 inches in length giving compatible Bond Arms derringers the flexibility to fire either cartridge interchangeably without any additional parts. Finished in matte stainless steel the barrel resists corrosion from regular handling and exposure to the elements while keeping glare down for discreet carry. Bond Arms barrels are built to the same exacting tolerances as the company s complete derringers ensuring proper fit and reliable function once installed. Swapping barrels is one of the signature features of the Bond Arms platform letting owners adapt a single frame to multiple calibers. Because Bond Arms derringers are designed around an interchangeable barrel system this .357 Mag/.38 Spl barrel can be swapped onto a compatible frame without gunsmithing giving owners an affordable way to expand their caliber options. The 2.5 inch length keeps the derringer compact and easy to conceal while still delivering usable performance from either chambering. Matte stainless construction also simplifies cleaning after firing since the finish stands up well to powder residue and moisture without the shine of a polished finish. Bond Arms owners looking to add a versatile .357 Mag/.38 Spl option to their derringer will find this barrel a straightforward upgrade available for sale at GrabAGun.
