Smith & Wesson is releasing a new pistol caliber carbine, the S&W Response. The Response is the first pistol-caliber carbine (PCC) from Smith & Wesson to be based on the popular AR-15 chassis, which makes it compatible with many existing parts and accessories for other PCCs. Chambered in 9mm, the Response has a 23-round capacity right out of the box and ships with two 23-round M&P double-stack magazines. One of the unique features of this new carbine is rooted in its innovative and easy-to-install Flexmag System, which consists of interchangeable magazine-well adaptors that allow the firearm to operate using a variety of Smith & Wesson and other manufacturer magazines. Included with the Response are two FLEXMAG kits that are compatible with either 9mm M&P double-stack or Glock-style 9 mm magazines.

The Response has a 16.5-inch threaded barrel surrounded by a polymer handguard that has Picatinny-style rail on top and M-Lok slots on the sides and bottom. At the rear, there is a Magpul MOE SL adjustable stock, and in front of that there is a flat face trigger and an M&P grip with four interchangeable palmswell adapters. The Response has an overall length of 35.38 inches fully extended and weighs just under 6 pounds.

“The Smith & Wesson Response is our solution for the PCC shooter that enjoys MSR platforms and prefers interfacing capabilities with various pistol magazines available in the market today. Its compatibility with the vast network of MSR aftermarket accessories allows the user to easily customize the Response to their specific preferences and needs. Smith & Wesson listened to the consumer and our goal was to deliver a completely versatile pistol caliber carbine that would be a perfect companion to your sidearm. This design is our response,” said John Myles, Senior Product Manager.
