The Shield Arms Z9 is a 9-round steel magazine built specifically for the Glock 43. It's engineered with a staggered geometry that lets you fit three extra rounds into a magazine that's the same overall length as the factory 6-round mag with pinky extension. You get all that extra capacity without changing your gun's profile for carry.
Each mag is constructed from heat-treated steel and finished with a Powercron cationic epoxy coating that resists corrosion in wet environments, humidity, and salty conditions. The magazines feature an impact-resistant base pad and witness holes on the side so you can quickly check your round count at a glance. The high-tensile steel spring and polymer follower work together to keep your rounds lined up and feeding clean through most standard 9mm loads.
This 3-pack combo includes three Z9 magazines and one black nitride steel mag catch. Shield Arms specifically recommends upgrading to their steel mag catch for maximum reliability with these magazines instead of relying on the factory plastic version. Made in the USA with a lifetime warranty against manufacturing defects, the Z9 is the go-to upgrade for people who want to squeeze more rounds into their compact Glock 43 without adding bulk.
Shield Arms strongly recommends upgrading to their steel mag catch, which is included in this 3-pack combo. The factory plastic Glock mag catch may not hold these extended magazines with full reliability. Using the recommended steel catch ensures the magazine seats and releases properly every time.
The Z9 is designed to be the same overall length as the factory Glock 43 magazine with a pinky extension, so it adds minimal extra length to your gun's grip. Most people find it adds just a small amount to the overall profile while giving you three extra rounds compared to the factory magazine.
The Z9 holds 9 rounds and has a visible pinky extension on the base pad, adding slightly to grip length. The Z8 holds 8 rounds and stays completely flush with your gun's grip. Both use the same design philosophy of fitting extra rounds into a compact package, so choose based on whether you prefer the extended grip of the Z9 or the concealment of the Z8.
The Z9 uses a high-tensile steel spring and polymer anti-tilt follower designed for smooth feeding with standard 9mm ammunition. Most users report reliable performance once the magazines are paired with the recommended steel mag catch. Like any upgraded magazine, it's wise to test them in your specific gun at the range to confirm compatibility with your ammunition.
Technically yes, but Shield Arms does not recommend it. The factory plastic mag catch may not engage the Z9 magazine properly, leading to potential feeding or retention issues. The steel mag catch included in this combo is engineered specifically for these magazines and ensures reliable performance.
This combo includes three Z9 magazines and one black nitride steel mag catch. The mag catch is designed specifically for the Z9 magazine and provides reliable engagement and release. Some retailers may sell 3-packs with three mag catches instead, so verify what you're purchasing before ordering.
