Bond Arms Barrel Features This Bond Arms replacement barrel measures 3.5 inches and is chambered in 9mm Luger giving derringer owners an additional caliber option for their existing frame. The satin stainless finish offers a bright polished look while still standing up to daily carry and handling. Because it fits directly into any original Bond Arms hand cannon frame aside from the Stinger installation is a simple drop-in swap with no special tools required. Adding a 9mm barrel to a Bond Arms derringer opens up ammunition options that are widely available and generally more affordable than some of the larger proprietary chamberings. Bond Arms machines every barrel to close tolerances and this one carries the same fit and finish quality shooters expect from the factory-original barrels. Owners who want to change up their derringer s caliber or simply prefer the appearance of a satin stainless finish get a barrel built to genuine Bond Arms standards. The barrel installs without gunsmithing letting shooters keep multiple barrels on hand and swap between them depending on the situation. This flexibility is why so many Bond Arms owners collect several barrels for a single frame.
