The ProMag 50-round drum delivers serious firepower when you need extended shooting sessions without constant reloading. This drum magazine holds 50 rounds of 9mm and locks right into Glock 17 and 19 platforms. The whole setup is engineered for reliability through proven design choices that have been field-tested by ProMag's USPSA competition team.
The drum body is molded from a proprietary DuPont Zytel polymer that balances weight savings with rugged durability. The upper housing uses heat-treated carbon steel with an over-molded design for added strength where it matters most. Inside, you get an injection-molded follower paired with a stainless steel spring that's precision-wound and heat-treated to handle the demands of extended mag use. This same follower system is shared with ProMag's AR-15 drum magazines, meaning it brings proven feeding performance from a larger platform down to the 9mm platform.
Loading the drum is straightforward. There's a winding system on the front that you twist slightly to release tension, then you load your rounds in. If you prefer not to hand-load all 50 rounds, you can use a Glock loading tool or grab an aftermarket magazine loader to make the job easier on your hands. Once it's wound up and locked in, the spring does its job feeding rounds smoothly through the mag follower.
Built right here in the USA, this drum carries ProMag's lifetime warranty against manufacturer defects. The precision assembly and quality control mean each mag gets checked multiple times during production. Whether you're running extended range drills, training sessions, or just want to cut down on reload interruptions, this 50-round drum works in Glock 17, 19, and several other Glock models that accept double-stack 9mm magazines.
Yes, this drum is designed to work seamlessly in both Glock 17 and 19 pistols. It's also compatible with Glock 26, 34, and other firearms that accept double-stack 9mm Glock magazines, including some 9mm pistol-caliber carbines like the Ruger PC9 and Kel-Tec Sub-2000.
Loading is user-friendly. Twist the wheel on the front of the mag slightly to release tension, then drop your rounds in one at a time. If you want to save your thumbs from hand-loading 50 rounds, you can use a Glock loading tool or an aftermarket magazine loader to speed up the process.
This is an aftermarket magazine made by ProMag. It's not manufactured by Glock, though it's designed to work reliably in Glock pistols. ProMag backs it with a lifetime warranty against manufacturer defects and has field-tested the design with their USPSA competition team.
The drum measures approximately 14.5 inches in overall length. The width is around 6.6 inches and the height about 3.2 inches, making it compact enough to handle despite holding 50 rounds compared to standard Glock magazines.
