The Promag Taurus GX4 9mm 50-round drum magazine is a high-capacity feeding solution for shooters who want extended shooting sessions without frequent reloads. Built for the Taurus GX4 platform, this drum magazine delivers significantly more rounds downrange than standard single-stack mags, making it a solid choice for range training, competition practice, or defensive preparedness where you want to minimize magazine changes.
Drum magazines require a different approach than box mags—they're bulkier, they need proper loading technique to avoid feeding issues, and they demand regular cleaning to run reliably. That said, when maintained well, a quality drum can be a force multiplier at the range. The 50-round capacity means longer trigger time between changes, which is especially valuable if you're working through drills or zeroing setups and don't want to break rhythm.
This is a Pro Mag product, a brand known for pushing capacity in the aftermarket magazine space. Before your first range trip, test-load and function-check the drum with your GX4—drum feeding can be finicky depending on shooter technique and gun condition, so confirm reliable feeding with your specific firearm before relying on it for carry or serious defensive use.

No—this magazine is designed specifically for the Taurus GX4. Do not attempt to use it in other pistols without confirming compatibility with your firearm's manufacturer.
Drum magazines should be loaded carefully to avoid over-compression and spring fatigue. Store fully loaded or completely empty rather than partially loaded for extended periods. Clean the drum regularly, especially the feed lips and follower, to ensure reliable feeding.
Drum magazines are generally considered range and training tools rather than primary carry mags. Test-fire extensively with your GX4 to confirm reliability before using it for any serious purpose. Standard single-stack magazines are often preferred for defensive carry due to their more predictable performance.
