Bond Arms Barrel Features The Bond Arms Barrel is machined to fit the Bond Arms frame system giving owners a straightforward way to add the classic .45 Colt chambering to an existing derringer. The .45 Colt cartridge has a long history in revolvers and single shot firearms offering a substantial payload with manageable pressure for a break open pistol. At 3.5 the barrel provides a longer sight radius than Bond Arms s shortest offerings improving practical accuracy while keeping the pistol compact. This combination of length and chambering makes the barrel well suited to both range use and backup carry. Finished in satin stainless this barrel has a smooth lightly polished surface that gives it a refined look compared to a matte or rough finish. Owners who already have a Bond Arms frame can add this barrel to introduce .45 Colt capability without purchasing an entirely new firearm. The simple drop in design makes barrel swapping accessible to anyone already familiar with the Bond Arms system. The Bond Arms Barrel is for sale at GrabAGun for derringer owners who want the classic performance of .45 Colt.
