Bond Arms Roughneck Barrel Features The Bond Arms Roughneck Barrel is chambered in 9mm Luger and measures 2.5 inches matching the compact profile Bond Arms derringers are known for. The Rough and Tumble finish gives the stainless steel barrel a distinctive textured surface that resists fingerprints and adds a rugged aesthetic compared to a standard polished finish. Because Bond Arms pistols use an interchangeable barrel system swapping to this 9mm barrel lets an owner reconfigure their derringer for a different cartridge without purchasing a second complete pistol. This modularity is a hallmark of the Bond Arms platform and a major reason shooters build out multiple barrel options over time. Installation is straightforward for anyone familiar with the Bond Arms barrel-swap system requiring no gunsmithing to complete. The 9mm Luger chambering offers shooters an affordable widely available round for practice or defensive carry in a compact derringer format. A non-threaded barrel keeps the profile clean and pocket-friendly for concealed carry applications. For Bond Arms owners who want to add a 9mm option to their derringer the Roughneck Barrel is available for sale at GrabAGun.
