The Smith & Wesson Response 9mm pistol-caliber carbine (PCC) is a lightweight and modular firearm designed to integrate seamlessly with the M&P pistol ecosystem, offering compatibility with M&P and Glock magazines. Its construction features a polymer body, a threaded 16.5-inch barrel, and comfortable ergonomics with a Magpul stock. During testing, it demonstrated reliability and accuracy, with zero malfunctions over 600 rounds. However, it currently only offers 9mm caliber, with no pistol or SBR variants available. Priced at approximately $800, the Response provides notable value with its Flex-Mag system and robust build, appealing to users seeking practicality in a PCC.
