The ProMag FN 509 9mm 50-round drum magazine transforms your FN 509 into a high-capacity range workhorse or competition shooter. If you run serious volume at the range or need extended firepower without reloading, a 50-round drum cuts drastically into your downtime and keeps you focused on precision rather than magazine changes. This is the magazine for shooters who want to maximize trigger time and get the most out of training sessions.
ProMag builds these drums with the same American-made discipline applied to their standard magazines: heat-treated chrome silicon wire springs precision-wound for reliable feeding, a heat-treated steel body with black oxide finish for durability, and an injection-molded follower that's been vetted through the assembly process. Every step gets checked and double-checked to ensure consistent function when you need it. The black oxide coating resists corrosion, and the robust construction handles the wear that comes with high-round-count days.
Sized specifically for the FN 509 9mm platform, this drum magazine fits the profile and feed system of that pistol. The substantial capacity makes it ideal for range sessions, training drills, or competition formats where magazine limits aren't enforced. The trade-off is bulk and weight compared to standard single-stack mags—you're gaining rounds at the cost of concealability and quick reloads—but for stationary shooting or sport applications, that's an easy tradeoff.
Built in the USA and backed by a lifetime guarantee against manufacturer defects, the ProMag FN 509 drum combines American manufacturing with the kind of straightforward reliability that keeps shooters coming back to ProMag.
