    Anodized Shield Arms +3 mag extension for the Z9 magazine.  12 coil plus power spring included.

    The Z9 magazine is our own 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 (150% OEM capacity!).  Our unique, easy access floor plate design allows you to quickly access the spring and follower without having to remove the extension from the magazine body. Comes with a 100% lifetime warranty, and the Shield Arms Spring for Life guarantee.

    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 footprintWe accomplished this increased capacity with our patent-pending magazine geometry, allowing the rounds to stagger, thereby fitting more in the same amount of space.

    All Shield Arms magazines and extensions are PROUDLY Made in the USA!

    *ODA Green

    ODA's (Operational Detachment Alpha) are the boots on the ground operational teams of a Special Forces Group. This color began as a special run for a deployed ODA. In continued support we have decided to continue the color as a standard offering and donate a portion of the proceeds to The Green Beret Foundation
