Bond Arms Barrel Features This Bond Arms replacement barrel measures 3.5 inches and is chambered for .45 Colt and .410 GA with a 3 inch chamber giving owners the option to run shotshells or .45 Colt cartridges from the same derringer. The stainless finish resists wear and corrosion during regular carry and handling keeping the barrel looking sharp through years of use.

Owners looking to change up their carry gun's caliber or simply give it a different look with a 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.
