Glock 21 45ACP • Capacity: 13 Round, Gen 4 • Manufacturer: Glock
This magazine fits the Glock 21 and 21SF and will also function in a Glock 30 and 30SF, but will not sit flush with the bottom of the mag well.
Often overlooked, the magazine is one of the most critical components of a pistol. The GLOCK precision-made, stagger-column, high-capacity device is designed to reliably feed all ammunition types. Lightweight and strong, with a polymer shell enclosing a metal liner, this easy to disassemble magazine insert is engineered to be a strong and secure unit for years of outstanding performance.
