Henry Repeating Arms H017BDM Big Boy .357 Magnum 4" 6-Round Revolver

The Henry Repeating Arms H017BDM Big Boy .357 Magnum 4" 6-Round Revolver is a compact, rugged sidearm engineered for law enforcement backup duty, civilian self-defense, and tactical training environments. Built by Henry—a manufacturer with deep roots in American firearms heritage—this revolver combines the stopping power of .357 Magnum with the reliability demanded by professionals who depend on their gear under pressure. The 4-inch barrel length balances velocity retention with practical concealability, making it suitable for duty carry or home defense without the bulk of full-sized wheelguns.

The H017BDM features a six-round cylinder chambered in .357 Magnum—capable of firing both full-power .357 loads and lower-recoil .38 Special ammunition for training or reduced-power applications. At 2.83 pounds, the revolver maintains substantial weight for recoil management while remaining light enough for extended carry without fatigue. The 4-inch barrel generates optimal velocity for .357 Magnum performance, typically delivering 1,200+ fps with standard loads—more than sufficient for duty-level ballistic performance. The compact profile, measuring 7.5 inches in overall length, fits standard holster options and allows secure retention across multiple carry modes.

This revolver benefits operators, armed security professionals, and civilian shooters seeking mechanical simplicity and consistent ignition without magazine dependency. The six-round capacity satisfies defensive scenarios while the double-action/single-action trigger system provides both safety and controllable shot placement at defensive distances. Law enforcement agencies utilizing revolver-platform secondaries will recognize the H017BDM's compatibility with standard duty leather, speedloaders, and mainstream training protocols. Ammunition selection remains abundant across retail and online channels—both .357 Magnum and .38 Special loads are widely available from major manufacturers.
