Product Announcement: The Shield Arms Glock 43 Z9 Magazine

Not too long ago Shield Arms released the S15 Magazine for the Glock 43X. This revolutionary little mag brought the 10rd capacity of the slim pistol to 15, in line with its fatter older brother, the Glock 19. On the 18th of May, Shield Arms will be adding the Glock 43 Z9 magazine to their lineup. As the name implies, this is for the standard Glock 43 and brings the capacity up to 9 rounds in a mag that’s the same size as the OEM mag with a pinky extension. Our favorite guntuber James Reeves has a video showcasing this new mag. I suggest you give it a watch.

More from Shield Arms @ TFB:

According to the Glock 43 Z9 Magazine Product Page:

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.

Finish Options


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 S15 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.


  • 9 round capacity
  • Same length as an OEM Glock 43 magazine with pinky extension
  • Easy to remove, impact resistant base pad
  • High lubricity finish, Black Oxide coating
  • Made in the USA

This might get some people to let their standard Glock 43’s out of the safe and into the streets again after its hotter, taller, sister the 43X showed up. Let us know what you think about the Glock 43 Z9 magazines in the comments below!

    It’s a bad idea. I’d say it’s a stupid idea but that might offend someone, so let’s just stick with bad.

    Let’s start with needing to replace the plastic factory mag release with a metal release because the metal mag will damage the plastic release But it doesn’t stop there because now a metal release is in a plastic gun. When the metal mag damages the plastic release, that’s a minor fee But when the metal release damages the frame, that means a whole new gun. Next switching to the metal release means you can’t use factory mags any more, so you’re stuck buying more of their mags which cost more than Glock mags.

    Next let’s remember that we whined for Glock to bring out a 10 round gun for places that have limits and making high cap mags will cause those guns to be thought of as high cap guns. But most of all if you feel the need for more than 10 rounds maybe the 43x isn’t for you. BTW it wasn’t for Glock either since it voids the warranty

    OMG...just get the G26 and have 10 rnds "AND" also be able to run any capacity 9mm magazine(15,17,33rnd) as a spare mag without damaging the frame with a steel mag release button.
    I also own a G43 but I understand It's limitations when I bought It.
    Just my 2 cents.
