This combo includes (1) Z9 magazine and (1) black nitride steel mag catch/release.
The Z9 magazine is a 9 round magazine for the Glock 43. The Z9 is a steel magazine, and is the same length as the OEM Glock magazine with pinky extension, but holds an additional 3 rounds.
Increased Capacity, Same Reliability
Glock pistols and magazines are known for reliability - the Z9 maintains that same Glock reliability while giving you a 50% increase in magazine capacity in the same overall footprint.
Shield Arms accomplished this increased capacity with their patent-pending magazine geometry, allowing the rounds to stagger, thereby fitting more in the same amount of space.
