The Smith & Wesson Response is a 9mm pistol-caliber carbine built around the familiar controls and modular ergonomics of a modern sporting rifle. Its FLEXMAG system uses interchangeable magazine well adapters for Smith & Wesson M&P double-stack and Glock G17 and G19 magazines, providing broad magazine compatibility. The blowback-operated semi-automatic action, adjustable stock, M-LOK handguard, and Picatinny-style top rail support a flexible range and defensive configuration. A 16.50-inch steel barrel features a 1/2x28 threaded muzzle with a thread protector, while the polymer receiver keeps the unloaded weight at 5.90 pounds.
