Fits the Glock® 43. Runs With a Steel Mag Catch.

The Z8 fits the single-stack Glock® 43. It's a steel magazine and isn't built to run on the polymer catch the pistol ships with, so install our Standard or Premium Z-Series steel catch. The Z-Series Dual Mag Kit includes one with a Z8 and a Z9. Running a Glock® 43X or 48? See the S-Series.

What Is the Shield Arms Z8?

The Z8 is an 8-round steel magazine for the Glock® 43 that sits flush with the grip, the same length as the 6-round factory magazine. That's two more rounds with no change to how the pistol carries. It runs with a Shield Arms Z-Series steel mag catch and is made in the USA with a lifetime warranty and Spring for Life.

  • Capacity: 8 rounds of 9mm
  • Fits: Glock® 43
  • Length: flush, same as the factory magazine
  • Requires: a Shield Arms Z-Series steel mag catch
Z-Series

Eight Rounds. Nothing Below the Grip.

People carry the Glock® 43 because it disappears: slim slide, short grip, nothing to snag or print. Every extended magazine gives some of that back. The Z8 doesn't.

It's the same length as the factory flush magazine and holds eight instead of six. The steel walls are thinner than polymer, and that's where the room comes from. Load it, seat it, and the pistol looks and carries exactly the way it did before, with two more rounds.

Features

Why It Holds 8

  • Steel Body

    Heat-treated steel walls are thinner than polymer, which makes room for two more rounds.

  • Flush Fit

    The same overall length as the factory Glock® 43 magazine. Nothing hangs below the grip.

  • Powercron Finish

    A corrosion-resistant epoxy electrocoat for sweat, humidity and daily carry.

  • Easy-Remove Base Pad

    Impact resistant, and it slides off for cleaning and spring service.

Glock® 43 Capacity

Eight Flush. More When You Want It.

The Z8 is our flush magazine, built for carry with nothing below the grip. Want more and don't mind pinky length? The Z9 holds 9, and takes a +3 extension for 12.

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

Run It With a Steel Mag Catch

The Z8 is steel and the catch your Glock® 43 shipped with is polymer. We build the Z-Series to run steel on steel, with our Standard or Premium Z-Series catch, both made in the USA. The Premium sticks out slightly further for an easier reach and engages the magazine slightly more. Either way it's a one-time install, and our installation guides walk you through it.

Powercron Finish

Powercron is 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

Z8 FAQ

Which pistols does the Z8 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.

Is it really flush?

Yes. The Z8 is the same overall length as the factory 6-round magazine and sits flush with the bottom of the grip.

Do I have to replace my mag catch?

Yes. The Z8 is built to run on a Shield Arms Z-Series steel catch, not the factory polymer catch. Install the Standard or Premium, or start with the Dual Mag Kit, which includes one.

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.

How does it fit 8 in the same space?

Steel walls are thinner than polymer, which leaves more room inside for rounds without changing the outside dimensions.

Z8 or Z9?

The Z8 holds 8 flush, for the shortest grip. The Z9 holds 9 at the length of a factory mag with a pinky extension. Many owners carry the Z8 in the pistol and the Z9 as the reload, and the Dual Mag Kit includes one of each plus the catch.

Are there extensions for the Z8?

No. The Z8 is built to be our flush magazine. For more capacity, the Z9 takes Z9 +1 and +3 extensions for 10 or 12 rounds.

How do I clean it?

Slide off the base pad, remove the spring and follower, and wipe everything down. Reassembly is the same in reverse. See our installation guides for more.

What is Spring for Life?

Free replacement magazine springs for as long as you own your Z8. See the program.

What's covered?

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

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.
