Promag
The ProMag DRMA64 is a 50-round drum magazine for .40 S&W handguns, engineered for shooters who want extended capacity without frequent reloads. Built from durable black polymer, this drum-style mag offers a practical upgrade for range sessions, training, or competition shooting where volume matters. If you run a .40 S&W and you're tired of swapping standard mags every 15 rounds, a 50-round drum transforms your shooting experience—you stay on target longer and spend less time fumbling with fresh magazines.
Drum magazines operate on a spring-and-follower system: as rounds feed up, the drum rotates incrementally to present the next cartridge to the feed lips. The DRMA64's polymer construction keeps weight down compared to steel alternatives, making it easier to manage the added bulk during extended shooting sessions. ProMag drums are designed for reliable feeding, though like any high-capacity magazine, regular cleaning and proper loading technique matter.
This is a single magazine—what you get is one 50-round drum. Compatibility is caliber-specific, so confirm your .40 S&W platform accepts ProMag drums before purchase. They're popular with competition shooters, home-defense minded folks who practice heavily, and anyone looking to maximize trigger time between reloads. Not legal in all jurisdictions; check local and state magazine capacity laws in your area before buying.

| Caliber | .40 S&W |

The DRMA64 is designed for .40 S&W platforms, but specific firearm compatibility can vary by manufacturer and model. Verify your handgun accepts ProMag drums before purchasing—contact ProMag or your gun's manufacturer if you're unsure.
Magazine capacity limits vary by state and locality. Some states and municipalities restrict magazine capacity to 10, 15, or other thresholds. Check your local and state laws before buying—it's your responsibility to comply with regulations in your jurisdiction.
You receive one ProMag DRMA64 50-round drum magazine. No additional accessories or magazines are included.
Drum magazines use a rotating follower system: as you fire, the spring pressure rotates the drum incrementally, presenting each new round to the feed lips. Proper loading, regular cleaning, and a reliable feeding handgun are key to consistent performance. Like any magazine, quality maintenance improves reliability.
