Iver Johnson Arms Glock Full-Size .40 S&W 50-Round Drum Magazine- Polymer Black

The Iver Johnson GLOCk drum magazine is made specifically for Iver Johnson by KCI in South Korea. This magazine is made from high quality impact resistant polymer and features a heavy steel spring with a quality stainless steel follower. The follower looks very similar to a cartridge which helps with loading the magazine. The magazine features a matte black finish.

The loading and unloading process for this magazine can be a bit confusing but the key is to keep tension on the follower and load each round one at a time. Once you have relieved the tension on the follower to load a round, DO NOT rotate the drum, DO NOT turn upside the drum, DO NOT flip the drum around or perform an action that would allow loose rounds already inside the body of the drum to tumble or rotate inside the inner track. The biggest cause of drum malfunctions is user error during the loading/unloading process. The spring inside is very large and is absolutely necessary in order to fight gravity and feed rounds upwards into the chamber of the GLOCK pistol.
