Bond Arms BABL42545410 Derringer45 Colt (LC)/.410 Satin 4.25" Stainless Steel

The Bond Arms 4.25" Snake Slayer IV barrel transforms your Bond Arms derringer into a longer-range capable backup or primary carry piece. This satin stainless steel barrel chamber combination in .45 Colt/.410 gives you genuine versatility: the proven stopping power of .45 Colt for precision shooting, plus the spread pattern of .410 shotshell for close encounters. At 4.25 inches, it's the longest barrel option in the Bond Arms lineup, adding sight radius and velocity while remaining compact enough for serious everyday carry or backup duty.

Bond Arms derringer barrels are modular—this barrel fits any standard original Bond Arms frame (the Stinger is the exception). So whether you're adding a second caliber option to an existing derringer, upgrading from a shorter barrel, or building out a dedicated .45 Colt/.410 setup, installation is straightforward and no gunsmithing is required. The satin stainless finish resists corrosion and looks professional without flash.

The .45 Colt/.410 pairing has a loyal following among those who value both precision and versatility in a small package. The longer 4.25" tube delivers better ballistics than shorter barrels, especially with .410 loads. This is a legitimate option for hunters, backcountry travelers, and shooters who want redundancy and adaptability in a lightweight, packable firearm.
