The ProMag FN Five-seveN 5.7x28mm 55-round drum magazine brings serious capacity to your FN Five-seveN pistol. If you shoot competition, train hard, or just want to minimize reload frequency at the range, a drum magazine transforms your Five-seveN from a capable defensive tool into a high-volume shooter's dream. ProMag has engineered this polymer drum to handle the unique demands of 5.7x28mm ammunition while maintaining the reliability you need when it counts.
Built in the USA, this magazine combines a proprietary DuPont Zytel-based polymer body with precision engineering throughout. The magazine spring is formed from heat-treated chrome silicon wire—the same approach ProMag uses across its lineup—and every assembly step is inspected and verified to ensure consistent quality. The flat dark earth finish blends seamlessly with modern tactical or duty setups, and the ergonomic design keeps the drum manageable despite its substantial round count.
ProMag backs every magazine with a lifetime guarantee against manufacturer defects, which reflects confidence in the assembly process and material selection. For Five-seveN owners who want to push round counts without fidgeting with standard single-stack mags, this drum delivers capacity without sacrificing the reliability that makes ProMag a trusted name in the industry.
