Smith & Wesson Response 9mm PCC 16.5" Threaded Barrel M-LOK

The Smith & Wesson Response pistol-caliber carbine transforms 9mm performance with its 16.5-inch threaded barrel and modular design system. This platform delivers rifle-length accuracy from pistol ammunition while maintaining compatibility with standard 9mm magazines through its innovative FLEXMAG adapter system.

What Makes This Different

Unlike traditional PCCs with fixed magazine wells, the Response features an interchangeable FLEXMAG adapter system that accepts multiple magazine types without modification. The 16.5-inch cold hammer-forged barrel provides significantly higher velocities than pistol-length barrels, while the M-LOK handguard offers unlimited accessory mounting options. The flat-face trigger delivers consistent break characteristics superior to standard curved triggers.

Key Features

• 16.5-inch threaded steel barrel with 1/2x28 threading for suppressors and muzzle devices
• M-LOK compatible aluminum handguard with full-length top rail
• Interchangeable FLEXMAG magazine well adapters (2 included)
• Flat-face trigger system for improved accuracy and consistency
• Interchangeable backstrap grip system for custom fit
• 10+1 capacity with included magazines
• Picatinny rail system for optics and accessories

The Response excels in competitive shooting environments where rapid target transitions matter. The 16.5-inch barrel generates approximately 200-300 fps higher velocities than 4-inch pistol barrels, extending effective range and terminal performance. The M-LOK handguard accepts bipods, lights, and grips without permanent modification. Weather-resistant construction handles adverse conditions while maintaining zero retention.
