Bond Arms Barrel Features This Bond Arms replacement barrel measures 3.5 inches and is chambered for .45 Colt / .410 GA with a 3 inch chamber giving owners the option to run shotshells or .45 Colt cartridges from the same derringer. The matte stainless finish resists wear and corrosion during regular carry and handling keeping the barrel looking sharp through years of use. Because it drops directly into any original Bond Arms hand cannon frame other than the Stinger installation requires no gunsmithing or special tools. Swapping calibers on demand turns one Bond Arms derringer into a genuinely versatile piece of everyday carry equipment. Bond Arms has built its reputation on quality derringer barrels machined to tight tolerances and this piece reflects that standard. Owners looking to change up their carry gun s caliber or simply give it a different look with a matte stainless finish get factory-level performance and reliability. The barrel ships ready to install letting shooters rotate between calibers depending on the situation without carrying multiple firearms. This flexibility is a big part of why Bond Arms owners keep multiple barrels on hand for their derringers.
