Bond Arms Barrel Features The Bond Arms replacement barrel is chambered to accept both .45 Colt and .410 GA shotshells giving owners the flexibility to switch between a hard-hitting handgun round and a shot load without changing frames. At 4.25 inches the barrel provides a longer sight radius than Bond Arms shorter barrel options which can help with practical accuracy at typical defensive distances. The matte stainless finish resists fingerprints and glare while standing up to the wear that comes with regular carry and range use. This dual-caliber design is one of the signature features of the Bond Arms derringer platform. Because the barrel fits any original Bond Arms derringer frame owners can add this caliber combination to an existing pistol without purchasing a new firearm. The ability to load .410 shotshells makes the barrel a popular choice for close-range defense against snakes and small pests while the .45 Colt option offers a proven harder-hitting round for personal protection. Bond Arms has built its reputation on this kind of caliber-swapping versatility in a compact all-metal derringer. For shooters who want one gun to cover multiple roles this barrel is a practical addition.
