Made in the USA, lightweight but incredibly strong, the PMAG D-50 GL9 - PCC is a highly-reliable, drum magazine for large-format pistols and pistol caliber carbines that feed from GLOCK pattern magazines. The Magpul D-50 GL9 PCC boasts many of the proven features of its 5.56 and 7.62 predecessors, the PMAG D-60 AR/M4 and PMAG D-50 LR/SR GEN M3, while providing the user with a similar magazine capacity increase. Providing 50-round capacity, the unique drum configuration keeps the height of the magazine manageable, allowing for prone firing and easier storage. For easy loading, it includes a ratcheting loading lever that removes tension from the internal spring. NOTE: This Mag is not compatible with Glock handguns, B&T GHM9, or KelTec Sub 2000)
