so much plastic! Smith & Wesson Response.
This review of the Smith & Wesson Response AR-9 platform highlights its extensive polymer construction, including the upper receiver and rail. The reviewer notes the innovative Flex Mag System, allowing for interchangeable magazine wells for M&P, Glock, and Sig P320 magazines. Despite initial concerns about polymer durability, the firearm has performed reliably over 800 rounds, though a safety recall for early production models is discussed.
