Magpul PMAG D-50 EV9 50-Round Drum Magazine for CZ Scorpion EVO 3 - 9mm Luger, Black Polymer

The Magpul PMAG D-50 EV9 is a 50-round drum magazine purpose-built for the CZ Scorpion EVO 3 and EVO 3+ in 9mm. If you run a Scorpion as your go-to PCC (pistol-caliber carbine) or want serious magazine capacity for range days and competition, this drum solves the reload problem—fifty rounds of 9x19mm Parabellum in a single magazine that still keeps your profile low enough for prone shooting. Magpul engineered this around the same reliability philosophy that made their AR and AK drums trusted by shooters: impact-resistant polymer body, stainless-steel guts that survive loaded storage, and a design that actually feeds.

Loading fifty rounds isn't a chore—the included ratcheting lever removes spring tension, so you're not fighting the mechanism. Once it's topped off, the high-visibility follower and rounds-remaining rear window let you track your ammo at a glance. The bolt hold-open feature locks the charging handle back on the last round, giving you that audible and tactile "mag is empty" signal on compatible Scorpions. Field maintenance is straightforward: the drum breaks down for cleaning without tools, then snaps back together in seconds.

Built from Magpul's next-generation polymer, the D-50 EV9 shrugs off the wear and tear of regular use—range trips, carbine courses, storage in a pack. The stainless internals won't corrode or lose spring tension even if the magazine sits loaded for months. Paint pen dot matrix on the side lets you mark rounds loaded or lot numbers if you're that meticulous. Bottom line: this is the drum magazine for Scorpion owners who don't want to compromise on reliability.

Frequently Asked Questions

Will the PMAG D-50 EV9 work with my CZ Scorpion EVO 3?

Yes. This drum is designed to fit CZ Scorpion EVO 3 and EVO 3+ magazine wells and is compatible with standard CZ Scorpion EVO 3/3+ magazine followers. The bolt hold-open feature works on firearms compatible with those standard followers.

What's the advantage of a drum magazine over standard mags?

The D-50 EV9 gives you fifty rounds before a reload—significantly more than traditional stick magazines—while the drum's unique design keeps the overall height manageable so you can still shoot prone or store it easily. That means fewer magazine changes during range sessions or competition.

Is the magazine easy to load?

Yes. Magpul included a ratcheting loading lever that removes tension from the spring as you load, making it much easier than manually compressing a spring drum. The lever and simple design keep loading stress-free and fast.

Can I leave this magazine loaded for long periods without losing function?

Yes. The stainless-steel internals are engineered to withstand long-term loaded storage with no loss of spring function or corrosion, so you can load it and rely on it month after month.
