Bond Arms Barrel Features The Bond Arms Barrel is chambered in 9mm and cut to a 3-inch length giving owners of compatible Bond Arms frames additional reach and sight radius over the shorter barrel options in the lineup. The rough stainless finish leaves a distinct less refined surface texture than a polished or satin barrel giving the gun a different look while retaining the same corrosion resistant stainless material. Because it is built to Bond Arms own barrel interchange system it swaps onto a compatible frame using the same simple process as any other Bond Arms barrel. This makes adding a new chambering straightforward for an existing owner. Bond Arms built its derringer platform around interchangeable barrels letting one frame serve multiple calibers without the cost of an entirely new firearm. This 9mm barrel brings a widely available moderate recoil cartridge into that lineup for practice or carry use. The 3-inch length offers a slightly longer sight radius than Bond Arms shortest options which can help with aim at typical defensive distances. It is available for sale at GrabAGun for Bond Arms owners adding a 9mm option to their derringer.
