Magpul PMAG D-50 EV9 CZ Scorpion (50-Round Drum)

The Magpul PMAG D-50 EV9 brings 50 rounds to the CZ Scorpion EVO 3 platform in a drum that actually loads and runs like a magazine. Most aftermarket drums for 9mm hosts trade reliability for capacity; the D-50 inherits the engineering Magpul refined on the AR-15 D-60 drum, so feeding is consistent across hollow points, flat-nose, and standard FMJ across all 9mm pressure ranges.

The ratcheting load lever is the feature that separates this drum from cheaper 50-round options. You ratchet the lever forward as you drop rounds in, and the spring tension is held off the column until the drum is full. This means you do not fight 50 rounds of compressed spring while loading the last 10, which is how follower-jump and feed lip stress kill cheaper drums. A high-visibility orange follower and a rear round-count window let you check status at a glance, and dual mag catch slots fit both EVO 3 and EVO 3+ magazine wells without modification.

At 14.6 oz empty and 50 rounds loaded, this is not a drum to clip on your belt for fast reloads. The use cases are range training where you want fewer reload cycles per session, home-defense ready mags where capacity beats speed, and any pin shoot or steel match where the 50-round window keeps you on the line. Pair with the factory or PMAG 35 EV9 mags for primary load and reload, and treat the D-50 as a sustained-fire option.
