Ruger Sr40c Pc Carbine 40 S W Extended Steel Floorplate

The Ruger 90368 SR40C 9rd Extended Floorplate 40 S&W magazine from Ruger is a blued steel, black-finished replacement and upgrade magazine engineered to fit the SR40C and Ruger PC Carbine platforms, offering a 9-round capacity with both the standard flat and extended floorplates for improved handling and faster reload ergonomics. Built from durable steel, this extended-type magazine maintains reliable feeding for .40 S&W rounds and features a robust follower and spring tension designed to hold consistent pressure under repeated use, making it well suited for range sessions, training drills, or back-up carry on compatible carbines. The low-profile flat plate preserves concealability when desired, while the extended floorplate provides extra purchase and easier magazine changes in timed scenarios; compatibility with Ruger SR40C model geometry ensures positive lockup and smooth insertion and removal. With a black finish that matches factory components and a design tailored to handgun-magazine form factors installed in pistol-caliber carbines, this magazine blends durability and practical function for shooters who want a factory-fit, steel magazine solution for their Ruger platform.
