A Drum Magazine for Your Glock Handguns
With Magpul's D-50 GL9 magazine, you won't have to complain about sore thumbs from reloading magazines, because most of your range session will fit into this bad boy. This 50-round drum magazine has been optimized for use on Glock handguns, and it's been built with the features from the company' other 9mm drum magazines, ensuring that you get the best possible performance while keeping that trigger finger happy.
The Magpul D-50 GL9 includes an increased feed-tower length, which makes it compatible with today's popular Glock models. The unique design of the drum makes the overall size of the unit more manageable, and there's a ratcheting mechanism for loading that saves your fingers when reloading 50 rounds. You can keep an eye on the number of rounds you have remaining, thanks to the rear round-count window and a rolling capacity indicator. The design will also lock your slide back, thanks to the built-in bolt hold-open device.
Magpul warns that users of the D-50 GL9 magazine with Gen 1-3 Glocks will likely need a new factory magazine release installed to support the drum's weight. Gen 4 Glocks will need a strengthened aftermarket magazine release, and all models may need a new extra-power recoil spring to ensure reliability. Use of the D-50 GL9 in pistol-caliber carbines is also not recommended, because of the height of the feed tower.
