The Kang-Petrov KPR-410 is a five-shot revolver with an oversized cylinder chambered to accept both .410 bore shotshells and .45 Colt cartridges. The weapon features a three-inch rifled barrel and a frame that is noticeably wider than conventional revolvers to accommodate the shotshell cylinder. It is, in practical terms, a pocket shotgun that can also fire pistol ammunition.

The Bailiff's versatility is its selling point. Loaded with .410 shotshells, it fires a spread pattern effective for close-range defensive scenarios where precise aiming under stress is unreliable — the same logic that makes shotguns popular for home defense, miniaturized into a revolver. Loaded with .45 Colt, it functions as a conventional heavy-caliber revolver with better accuracy at range. The ability to mix ammunition types in the cylinder — shotshells for the first two chambers, .45 Colt for the remaining three — gives the shooter both close-range spread and medium-range precision in a single weapon.

Kang-Petrov markets the Bailiff as 'the district court' — a weapon that renders judgment at any range. The weapon has become popular among bouncers, building security, and transit operators who face threats at variable distances in confined spaces. Its distinctive wide cylinder makes it instantly recognizable, which provides a deterrence factor that its modest ballistic performance might not otherwise warrant.
