Shield Arms +1 mag extension for the Z9 magazine. 11 coil plus power spring included.
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.
We accomplished this increased capacity with our patent-pending magazine geometry, allowing the rounds to stagger, thereby fitting more in the same amount of space.
Proudly made in the USA by Check-Mate.
Mag Catch Recommendation
We recommend swapping out your plastic OEM mag catch with either our standard steel mag catch or our premium steel mag catch. Here's why. If you don't swap your mag catch you may have reliability issues. If you use another manufacturer's mag catch you may have reliability issues.
- 9 round capacity
- Same length as an OEM Glock 43 magazine with pinky extension
- Easy to remove, impact resistant base pad
- Powercron finish
- Made in the USA
Powercron is a cationic epoxy coating that offers excellent corrosion resistance and low VOC in a lead-free film electrocoat surface finish. If you are in a humid or salt water environment, or if you sweat a lot, we recommend Powercron, Electroless Nickel, or Black Electroless Nickel finish.
Note: because we have multiple Powercron vendors, there may be slight cosmetic variations in the finish. This is cosmetic only and does not affect performance. If you are concerned about a "matching" finish from mag to mag, you might be happier with one of the electroless nickel finishes.
Like all Shield Arms products, our Z9 magazine comes with our 100% lifetime warranty against manufacturing defects. Additionally, we also offer a Spring for Life Guarantee - wear out your spring, get a new one for free, for life.
