Featuring a durable, stainless steel body with a corrosion-resistant blued finish and a chrome-plated steel spring/polymer follower combo, the GSG® MP40 9mm 25-Round Magazine offers smooth, jam-free operation and consistent field performance in virtually any environment. The high-tensile steel spring and polymer follower ensure smooth feeding operation, while the precision-machined feed lips deliver a snug, wobble-free fit for enhanced stability and reliable operation you can depend on. The steel floor plate is easily removed when maintenance and cleaning are required. Better yet, this GSG MP40-compatible magazine is manufactured to identical specs as the original MP40 magazines (with the exception of the follower and spring) for a period-correct look and feel.
