KCI USA® Gen 2 Glock®-Compatible 9mm 50-Round Drum Magazine – KCI-MZ027
The KCI USA® Gen 2 Glock®-Compatible 9mm 50-Round Drum Magazine (KCI-MZ027) is a heavily upgraded, high-capacity feeding system engineered to deliver commercial-grade ammunition payloads to Glock-pattern pistols and pistol caliber carbines (PCCs). While first-generation drum designs across the industry frequently suffered from binding internal components and brittle feed towers, this completely redesigned Gen 2 variant (851586008078) resets the bar. It strips away loading friction by utilizing an advanced structural framework built explicitly to survive continuous, high-volume tracking drills and sustained target strings without a hitch.
The core structural advancement of the KCI Gen 2 layout is its **heavy-duty, full-length internal steel reinforcement matrix**. Molded directly inside a rugged, impact-resistant high-tech polymer housing, this steel skeleton wraps completely up into the feed lips and locking notches to match standard factory Glock magazine tolerances. To make loading a massive 50-round payload stress-free, the back plate features an integrated, ergonomic **thumb-lever mechanical assist**. Pulling down on the tension lever manually compresses the internal high-tensile chrome-silicon spring, letting you drop in cartridges effortlessly without fighting cumulative spring pressure. Driving an advanced, non-marring rolling follower system, this drum feeds smoothly into compact or full-size handguns like the Glock 17, 19, 26, 34, and 45, as well as popular sub-guns like the Ruger® PC Carbine or custom AR-9 builds.
Includes: (1) KCI USA Gen 2 50-Round 9mm Glock-Compatible Matte Black Drum Magazine and Protective Dust Cap.
