Smith and Wesson 13800 Response 9mm Luger 16.5 inch 10 round plus 1 Steel

The Smith & Wesson 13800 Response brings a purpose-built pistol caliber carbine platform to shooters who want MSR ergonomics with 9mm economy, featuring a 16.5" steel 1:10" twist threaded barrel that accepts suppressed or compensator-equipped setups and a flat-face trigger that delivers a crisp break for fast, accurate follow-up shots; the Response series uses the innovative FLEXMAG System with interchangeable mag well adapters so you can run M&P double-stack and Glock 17/19 magazines for range drills, competition-style transitions, or compact home-defense setups without reworking your magazine inventory. The rifle-length M-LOK handguard and Picatinny-top rail let you mount optics and accessories where you need them, while ambidextrous thumb safeties and interchangeable backstrap grips make it comfortable for a wide range of shooters; the familiar MSR controls ease training and maintenance, and the 32.1"×35.4" overall length with a 5.9 lb weight yields stable handling for precision work and rapid strings. Built as a semi-auto, optic-ready 9mm PCC that requires FFL transfer, the Response is a versatile option for training, competition, and personal defense scenarios where magazine commonality and modularity matter.
