ProMag Walther P99 & SW99 9mm 50-Rd Drum Magazine - Black

The ProMag DRM-A70 is a high-capacity 50-round drum magazine engineered for 9mm Luger Walther P99 and Smith & Wesson SW99 series pistols, delivering extended firepower for range sessions, training drills, and recreational plinking.

The drum body is molded from a proprietary DuPont Zytel-based polymer with aggressive texturing that provides a confident grip during reloads. A heat-treated blue steel upper magazine tower feeds rounds into the action, paired with a heat-treated chrome silicon wire internal spring and an injection-molded polymer follower for smooth, reliable feeding round after round.

Finished in matte black, the DRM-A70 installs just like a factory magazine and gives shooters a serious round-count boost at the range on any compatible Walther P99 or SW99 9mm platform.
