Glock 23 40 S&W • Capacity: 13 Round, Gen 4 • Manufacturer: Glock

This magazine will also function in a Glock 27, 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.
