Shield Arms Z9 Glock 43 9mm 9-Round Steel Magazine - Black Oxide

The Shield Arms Z9 magazine is a purpose-built 9-round steel replacement for the Glock 43, delivering a 50% increase in capacity over the factory magazine while staying in the same footprint as an OEM Glock magazine with a pinky extension. Built from steel with a durable black oxide finish, the Z9 feeds reliably and resists wear from daily carry and range use alike.

This complete Z9PM9PC magazine ships with the +3 magazine extension preinstalled and an 11-coil plus power spring to ensure consistent feeding with 9mm Luger ammunition. The overall length mirrors a standard Glock 43 magazine with a pinky extension, so the pistol retains its compact carry profile while gaining three additional rounds. As with all Shield Arms Z-series magazines, the Z9 is engineered as a direct, drop-in upgrade for the Glock 43 platform.
