Compatibility

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

This kit fits the single-stack Glock® 43 only. The Z9 is a steel magazine and runs on a steel mag catch instead of the polymer catch the pistol ships with, so the kit includes one. Install it once and you're set. Running a Glock® 43X or 48? See the S-Series.

What Is the Z9 Starter Kit?

The Z9 Starter Kit is everything you need to run a Shield Arms Z9 in your Glock® 43: one Z9 9-round steel magazine and one black nitride steel mag catch. The Z9 holds three more rounds than the 6-round factory magazine at the length of a factory mag with a pinky extension. Both parts are made in the USA, and the magazine has a lifetime warranty and Spring for Life.

In the kit: (1) Z9 magazine, (1) steel mag catch
Fits: Glock® 43
Capacity: 9 rounds of 9mm
Extends to: 10 or 12 rounds

Everything You Need to Run a Z9

The Z9 puts nine rounds in a Glock® 43 at the length of a factory mag with a pinky extension. Thin steel walls make the room, and the magazine carries the same size you already do.

Steel magazines need a steel catch, so we put both in one box. Swap the catch, load the Z9, and every Z9 or Z8 you add later runs on the same catch.

Why a Steel Catch

Steel Mags Run on a Steel Catch

The Z9 is 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. Buy it with a Z9 on its own.

Powercron Finish

Questions

Z9 Starter 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.

Do I need anything else?

No. The kit includes the steel catch the Z9 runs on. Just install the catch and load the magazine.

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 step by step.

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.

Will the Z8 run on this catch?

Yes. The Z8 and Z9 use the same steel catch, so you can add either one later.

How do I get more than 9 rounds?

Swap the base pad for a Z9 +1 for 10 or a Z9 +3 for 12.

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. Want the Premium? Buy it with a Z9 Magazine instead.

What is Spring for Life?

Free replacement magazine springs for as long as you own your Z9. See the program.

What's covered?

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

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.
