The Glock 50981 magazine insert is a factory polymer component engineered to optimize your .45 ACP Glock platform experience. This black polymer insert fits the full-size G21, compact G21SF, and subcompact G30 in Gen5 configuration, making it a straightforward way to maintain factory-spec performance if your magazine needs replacement or upgrade. Whether you're running a duty rig, competition setup, or defensive carry, having a genuine Glock insert on hand ensures your magazine system stays reliable without having to source a complete mag.
As a dedicated .45 ACP component, this insert is engineered to the tolerances Glock built into these models—not a universal fit or aftermarket workaround. If you run Gen5 G21, G21SF, or G30 pistols, you're looking at a part that drops in without guesswork or fitting. It's the kind of spare component savvy shooters keep in their range bag or spare parts box, especially if you rotate multiple magazines or want a backup ready to go.
Glock's polymer construction delivers proven durability and consistency. This is OEM engineering for your platform, not a compromise part. Stock one now and keep your .45 running without interruption.
