The Smith & Wesson Response in 9mm Luger (brand part no. 13797) is a semi-automatic pistol-caliber rifle built around the innovative FLEXMAG system, pairing a 16.5-inch barrel with a 1:10-inch twist rate. Smith & Wesson threads the muzzle 1/2×28 with a thread protector, fits a flat-face trigger with a crisp break, and mounts a handguard with M-LOK slots and a top Picatinny rail. Two interchangeable FLEXMAG magazine well adapters let the rifle run M&P double-stack or Glock 17/19-pattern magazines, and it uses an ambidextrous thumb safety. The rifle ships without sights and includes two 23-round magazines. Among AR-platform rifles in the AR rifles category, the Response favors shooters who want magazine flexibility with higher-capacity magazines included.
