Bond Arms Barrel Features The Bond Arms replacement barrel is chambered in 10mm and finished in a bright satin stainless treatment that matches the classic look many Bond Arms owners prefer. At 3 inches this barrel keeps the derringer compact and easy to carry while delivering the significant power of the 10mm cartridge in a small package. Swapping barrels lets an existing Bond Arms owner add a new caliber to a single frame rather than purchasing an entirely separate firearm. The satin finish resists showing minor handling marks while still presenting a polished finished appearance. This barrel is designed to fit all original Bond Arms hand cannon frames though it is not compatible with the Stinger model. Changing barrels requires no gunsmithing letting the shooter reconfigure their derringer for different calibers depending on the situation or simply their preference that day. Because it shares Bond Arms fit and quality control standards this barrel installs and locks up exactly like the barrel it replaces. The 10mm chambering makes this barrel a popular choice among owners looking to pair their Bond Arms derringer with a common semi-auto handgun caliber they already load for.
