Genuine Glock factory magazine follower for .45 ACP G21 magazines. Black polymer construction. Essential replacement part for 10-round magazines.
Fits: Glock 21
This is the genuine factory magazine follower manufactured by Glock for their .45 ACP G21 platform. The follower is the critical component that sits atop your magazine spring, guiding rounds into the feed lips as you fire.
Magazine followers wear over time with repeated loading and unloading. A worn or damaged follower can cause feeding issues, double-feeds, or failure to feed. Replacing it with a factory Glock part restores your magazine to like-new condition.
Whether you're maintaining your duty magazines, competition gear, or personal defense setup, keeping spare factory followers on hand is smart practice. This is the part that keeps your ammunition moving reliably when it matters most.
