ProMag DRMA20 50-Round Drum Magazine 9mm Glock 43X/48 Polymer

The ProMag DRMA20 delivers extended firepower for Glock 43X and 48 pistols with its 50-round capacity in a durable drum configuration. This high-capacity magazine transforms compact carry guns into range-ready platforms without requiring modifications to the firearm itself.

What Makes This Different

Unlike standard 10-round factory magazines, the DRMA20 multiplies ammunition capacity by five times while maintaining reliable feeding through its proven drum mechanism. The DuPont Zytel polymer construction provides the strength of steel magazines at a fraction of the weight. Internal spring tension remains consistent throughout the entire 50-round capacity, ensuring reliable chambering from first round to last.

Key Features

• 50-round capacity increases firepower significantly over standard magazines
• DuPont Zytel polymer construction resists impact and environmental stress
• Drop-free design enables rapid magazine changes during range sessions
• Compatible with Glock 43X and 48 pistols without modifications
• Drum configuration distributes weight evenly for balanced handling
• Anti-tilt follower prevents feeding malfunctions and double-feeds
• Witness holes allow visual ammunition count verification

Range training benefits from extended shooting sessions without frequent reloading interruptions. Competition shooters gain tactical advantages in high-volume stages where magazine changes cost valuable seconds. The drum's low-profile design maintains reasonable concealability compared to extended stick magazines of similar capacity. Weather-resistant polymer construction handles temperature extremes and moisture exposure without degrading feed reliability.
