HFC 145Rd Polymer/Metal Drum Magazine for G-Series Gas Blowback Pistols & Glock GEN 3/4, Black/Brown

Gas blowback Glock pistols run on expensive magazines that hold around 30 rounds. You burn through them fast. The HFC drum gives you 145 rounds in one load, which is roughly five standard mags' worth without swapping during a game.

Capacity that actually matters. A typical GBB Glock mag holds 28–35 rounds. This drum holds 145. That means fewer reloads and less time fumbling for spares in the middle of a match. It's not a hi-cap wheel you wind—it's a drum you load and insert, so it stays silent and ready.

What it's built from. The body is polymer with metal internals. The construction is solid enough to handle repeated insertions and removals without cracking at the feed lips, which is where cheaper mags tend to fail first.

Compatibility. It fits Tokyo Marui G-Series gas blowback pistols, including Glock GEN 3 and GEN 4 replicas. It will not work with AEGs, CO2 pistols, or non-Glock platforms. If your gun takes standard TM GBB mags, this one should fit.

Before you buy. Drum mags are bulkier than stick mags. Depending on your holster setup, it may not fit in standard pistol pouches designed for single-stack or low-capacity mags. You're trading concealment and profile for capacity. The package includes the magazine only—no gun, no gas, no BBs.
