The Chiappa X-caliber 20ga/410/.45LC gauge adapter insert is a precision barrel insert designed for shooters and tactical professionals who demand multi-caliber versatility from a single firearm platform. This break-open adapter transforms a standard shotgun into a capable multi-gauge system, allowing operators to transition between 20-gauge, .410 bore, and .45 Long Colt ammunition without changing firearms. Built for law enforcement trainers, competitive shooters, and field operators, this insert eliminates the need to carry multiple weapons for varied training scenarios or operational requirements.
Manufactured by Chiappa with a fully rifled barrel measuring 8 inches in length, the X-caliber insert delivers consistent accuracy across all three calibers through precision rifling geometry optimized for each round. The blued finish provides corrosion resistance and a professional appearance suitable for tactical and duty applications. Manual extraction allows operator control over case removal—a feature preferred in tactical settings where smooth, deliberate weapon handling is paramount. The insert's compact 1.4-inch diameter and lightweight 0.37-pound construction ensure minimal impact on firearm balance and ergonomics when installed in compatible break-open shotgun receivers.
This adapter insert is recommended for use with any break-open shotgun equipped with an extractor mechanism, making it compatible with most traditional and modern break-action platforms. It is particularly valuable for academy firearms instructors who require flexible ammunition options during multi-level training courses, as well as for hunters and sport shooters seeking reduced-recoil alternatives to standard 12-gauge ammunition. Installation is straightforward, requiring only insertion into the barrel chamber of a compatible firearm. The manual extraction system demands operator familiarity, making this insert ideal for trained personnel in professional or experienced shooter environments.
