Magpul PMAG D-50 GL9 50-Round Drum for Glock 17

In the realm of modern firearms, few accessories offer a blend of reliability and innovation like Magpul's PMAG D-50 GL9. This drum magazine is engineered for those who demand unwavering performance from their 9mm Glock handguns. Constructed to be lightweight yet robust, this 50-round capacity marvel ensures that you remain in command during critical moments.

The design prowess seen in the PMAG D-60 AR/M4 and its sibling, the PMAG D-50 LR/SR GEN M3, has been thoughtfully adapted into this model for double-stack 9mm Glocks. The unique drum configuration balances substantial firepower with manageable height, making storage less cumbersome—a crucial advantage when seconds count.

Loading becomes an effortless task thanks to the ratcheting lever that alleviates spring tension. With every round accounted for via a rear window indicator and high visibility follower, you're always aware of your remaining ammunition—vital information when precision matters most.

An innovative bolt hold-open feature reliably locks back on empty magazines when used with compatible firearms designed around Glock pattern followers. However, it's essential to note installation recommendations: Gen 1-3 models should upgrade to a new OEM magazine release due to weight considerations; Gen 4 requires an aftermarket metal release for optimal functionality.

Additionally recommended is upgrading your recoil spring assembly—to ensure flawless feeding across varying firearm tolerances—which may necessitate an extra power recoil spring based on individual gun characteristics.

A word of caution: while tempting as it may be to use this magazine in pistol caliber carbines (PCC), such application isn't advised due to potential support issues within non-standardized mag wells leading possibly towards feed failures or excessive wear over time.
