Compatibility

Fits the Glock® 43X and 48. The Steel Catch Is Included.

This combo fits the Glock® 43X and 48, all generations. The S15 is a steel magazine, and the polymer mag catch the pistol ships with isn't compatible with it, so the combo includes our steel catch. Install it once and all three magazines run on it. Running a single-stack Glock® 43? See the Z-Series.

What Is the S15 Combo Pack 1?

S15 Combo Pack 1 is a full Glock® 43X / 48 carry setup: three Shield Arms S15 Gen 3 15-round steel magazines and the black nitride steel mag catch they run on. Each S15 fits 15 rounds flush in the 43X/48 grip, so three magazines give you 45 rounds with nothing hanging below the grip. Made in the USA, with a lifetime warranty and Spring for Life.

  • In the combo: (3) S15 Gen 3 magazines, (1) steel mag catch
  • Fits: Glock® 43X and 48, all generations
  • Capacity: 15 rounds per magazine, flush
  • Total: 45 rounds across three magazines
Carry + Spares

One in the Gun. One on the Belt. One for Training.

The S15 is the magazine that put Shield Arms on the map: 15 rounds, flush, in the slim Glock® 43X and 48. Combo Pack 1 is the simplest way to set up a full carry kit around it.

You get three identical S15s, one for the pistol, one for your reload and one for the range or the nightstand, so every reload feels the same. The steel catch comes in the box, so you swap it once and everything runs.

Why a Steel Catch

Steel Mags Run on a Steel Catch

The S15 is steel and the catch your 43X/48 shipped with is polymer, and the two aren't compatible. This combo 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.

Questions

S15 Combo Pack 1 FAQ

Which pistols does it fit?

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

Do I need anything else?

No. The combo includes the steel catch all three 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 polymer 10-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.

Combo Pack 1 or the Starter Kit?

The Starter Kit is one S15 and the catch, a way to try it. Combo Pack 1 is three S15s and the catch, enough for a full carry setup with spares.

Does it change how the pistol carries?

No. The S15 sits flush with the bottom of the grip, so your grip and holster stay the same.

How do I get more than 15 rounds?

Swap a base pad for an S15 extension: 17 with the +2, 20 with the +5 or 25 with the +10. Want extensions in the box? Combo Pack 4 adds two +5s.

Does it work in a grip-chopped pistol?

Yes. A 43X or 48 converted by our S10 Grip Chop Service runs the S15. Add a Grip Chop Sleeve to restore full grip length.

What is Spring for Life?

Free replacement magazine springs for as long as you own your S15s. See the program.

What's covered?

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