Fits the Glock® 43. The Steel Catch Is Included.

This kit fits the single-stack Glock® 43 only. Z-Series magazines are steel and run on a steel mag catch instead of the polymer catch the pistol ships with, so the kit includes one. Install it once and both magazines run on it. Running a Glock® 43X or 48? See the S-Series.

What Is the Z-Series Dual Mag Kit?

The Z-Series Dual Mag Kit is one Z8 and one Z9 steel magazine for the Glock® 43, plus the steel mag catch they both run on. The Z8 holds 8 rounds flush with the grip. The Z9 holds 9 at the length of a factory mag with a pinky extension. Carry the Z8 in the pistol and the Z9 as your reload, and you have 17 rounds in two magazines instead of 12. Made in the USA, with a lifetime warranty and Spring for Life.

  • In the kit: (1) Z8, (1) Z9, (1) steel mag catch
  • Fits: Glock® 43
  • Capacity: 8 flush, 9 at pinky-extension length
  • Total: 17 rounds across both magazines
Two Mags, Two Jobs

Flush to Carry. Longer to Reload.

Single-stack carriers usually want two things from a magazine. In the pistol, it should sit flush so the grip stays short and easy to hide. On the belt, it should hold as many rounds as possible and be easy to grab.

This kit gives you both. The Z8 rides in your Glock® 43 with 8 rounds and no added length. The Z9 rides in your mag pouch with 9 rounds and a full pinky grip for a fast reload. One steel catch runs them both.

Glock® 43 Capacity

From 6 to 8 or 9.

Thin steel walls leave more room inside than polymer, so the Z8 holds 8 in the factory flush length and the Z9 holds 9 at pinky-extension length. Add a Z9 +3 when you want 12.

Capacity laws vary by state and city. Check yours before you buy.

Why a Steel Catch

Steel Mags Run on a Steel Catch

Z-Series magazines are steel and the factory Glock® 43 catch is polymer. We build the Z-Series to run steel on steel, so this kit includes our Standard steel catch. It's a one-time install, and our installation guides walk you through it. Another manufacturer's catch may cause reliability issues. Prefer the Premium? It sticks out slightly further and engages the magazine slightly more.

Powercron Finish

Both magazines have a Powercron finish, a cationic epoxy electrocoat, lead-free and low-VOC, that holds up to sweat, humidity and salt air. We use more than one Powercron applicator to keep magazines in stock, so the sheen can vary slightly from batch to batch. Protection and performance are the same.

Questions

Z-Series Dual Mag Kit FAQ

Which pistols does it fit?

The single-stack Glock® 43. For the Glock® 43X and 48, see the S-Series. For the Glock® 19 and 17, see the DS-Series.

Which one should I carry in the pistol?

Most carriers put the flush Z8 in the pistol for the shortest grip and keep the Z9 as the reload, where the pinky-length body is easy to grab. If you already carry a pinky extension, the Z9 in the pistol works too.

Do I need anything else?

No. The kit includes the steel catch both magazines run on. Install the catch and load up.

How hard is the catch install?

It's a one-time swap with basic tools and no gunsmithing. Our installation guides walk you through it.

Will my factory 6-round mags still work?

They'll run with the steel catch, but we don't recommend it for regular use. Steel on polymer adds wear to the magazine over time.

Can I add capacity later?

Yes. The Z9 takes our +1 and +3 extensions for 10 or 12 rounds. Extra Z8s and Z9s run on the same catch.

Standard or Premium catch?

This kit includes the Standard. The Premium sticks out slightly further than the Standard, so it's easier to reach and press, and it engages the magazine slightly more.

What is Spring for Life?

Free replacement magazine springs for as long as you own your Z-Series magazines. See the program.

What's covered?

A lifetime warranty against defects in materials and workmanship, plus Spring for Life on both magazines.

ODA Green

Used on: magazine extensions, magwells

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. Finish is anodized in green.

QPQ Nitrocarburizing Surface Treatment

Used on: magazines, barrels, slides

QPQ Nitrocarburizing is a type of surface treatment used to enhance the durability and corrosion resistance of metal parts. The process involves heating the metal in a controlled environment, where nitrogen and carbon are introduced to the surface of the metal. This forms a thin layer of a hard compound called "nitrides," which increase the surface hardness of the metal.

During the QPQ Nitrocarburizing process, the metal is immersed in a special salt bath and heated to high temperatures. The salt bath contains a mixture of chemicals that release nitrogen and carbon, which penetrate the surface of the metal. The process is carefully controlled to ensure that the nitrogen and carbon penetrate to a specific depth, creating a uniform layer of nitrides on the metal's surface.

The resulting nitride layer provides many benefits to the metal parts, including increased hardness, wear resistance, and corrosion resistance. This treatment helps to increase the lifespan and durability of metal parts, making them more reliable and long-lasting.

Any “scuffing” you see in the surface finish is completely normal, and will not affect the durability or corrosion resistance of the steel.

Electroless Nickel Plating

Used on: magazines

Silver electroless plating offers superior electrical conductivity and corrosion protection with excellent deposit uniformity and adhesion properties. This bright, reflective finish provides outstanding solderability and contact resistance while maintaining the consistent thickness and coverage that electroless plating processes are known for. Black electroless nickel plating provides these same exceptional deposit properties - including lubricity, hardness, and corrosion resistance - but with a fully conductive and uniform black surface finish that combines superior performance with an attractive dark appearance.
