Magpul PMAG D-50 GL9 9mm 50-Round Drum Magazine for Glock-Compatible PCC - Black Polymer$112.03
Availability: In Stock
The Magpul PMAG D-50 GL9 is a 50-round drum magazine purpose-built for 9mm Glock handguns. If you're running a stock Glock and want serious round capacity without a magazine that dominates your setup, this is the drum that breaks the mold. The D-50 GL9 trades the unwieldy height of older drum designs for a profile that actually works with standard holsters and storage—you get five times the ammo of a typical 10-rounder in a form factor that doesn't feel like an accessory from another platform.
The magazine is loaded with practical features that reflect Magpul's decades of drum-magazine engineering. A ratcheting loader lever pulls back spring tension so you're not white-knuckling each round into the stack. The rear witness window, high-visibility follower, and capacity indicator roller let you track your rounds at a glance. When you run the gun dry, the innovative bolt hold-open feature locks the slide back—as long as your Glock is configured to respond to Glock-pattern followers. Disassembly is straightforward for cleaning and maintenance, and the drum is USA-made from proven polymer that handles the weight and abuse of actual use.
Before you load one up, understand the setup: Gen 1–3 Glocks benefit from a fresh OEM magazine release to handle the extra weight; Gen 4 models need an aftermarket metal release. Magpul also recommends running a new or upgraded recoil spring assembly to ensure reliable feeding—some guns may need extra-power springs depending on how your individual pistol runs. Critically, this drum isn't designed for pistol caliber carbines; the feed-tower geometry will stick up unsupported in most PCC magazine wells and risks premature wear or feed failures.
Built for Glock shooters who want capacity, reliability, and thoughtful engineering—not hype.
| Brand | Magpul |
| Model | PMAG D-50 GL9 |
| Caliber | 9x19mm Parabellum (9mm) |
| Capacity | 50 rounds |
| Compatibility | Double-stack 9mm Glock handguns |
| Magazine Type | Drum |
| Material | Black polymer |
| Country of Origin | USA |
The D-50 GL9 fits all double-stack 9mm Glocks. However, due to the drum's extra weight, Magpul recommends installing a new OEM magazine release on Gen 1–3 models. Gen 4 Glocks require an aftermarket metal magazine release. A new or upgraded recoil spring assembly is also strongly recommended for reliable feeding; some guns may need extra-power springs depending on your specific pistol.
No. Magpul does not recommend using the D-50 GL9 in PCCs. The increased height of the feed tower sits unsupported in most pistol caliber magazine wells, which can cause premature wear on the magazine catch and lead to feeding failures or improper round presentation—especially in firearms with non-standard magazine well specs.
The magazine includes a ratcheting loading lever that removes tension from the internal spring, making it easier to load all 50 rounds. The drum disassembles for cleaning and is field-maintainable. It features a rear witness window and capacity indicator roller to track remaining rounds.
You receive the Magpul PMAG D-50 GL9 drum magazine. Any Glock modifications (magazine release, recoil spring) are sold separately and must be sourced based on your specific pistol generation.
