Ten Magazines. The Steel Catch Is Sold Separately.

This pack is ten S15 Gen 3 magazines for the Glock® 43X and 48, all generations. It doesn't include a mag catch. The S15 is steel, and the polymer catch the pistol ships with isn't compatible with it, so every pistol that runs these needs our Standard or Premium steel catch. Starting from scratch? Combo Pack 1 includes the catch.

What Is the S15 Combo Pack 6?

S15 Combo Pack 6 is ten Shield Arms S15 Gen 3 15-round steel magazines for the Glock® 43X and 48, our largest S15 pack. Each S15 fits 15 rounds flush in the 43X/48 grip, so the pack holds 150 rounds. The magazines have a black Nitrocarb finish and run on a Shield Arms steel mag catch, sold separately. Made in the USA, with a lifetime warranty and Spring for Life on every magazine.

  • In the pack: (10) S15 Gen 3 magazines
  • Fits: Glock® 43X and 48, all generations
  • Capacity: 15 rounds per magazine, 150 total
  • Requires: a Shield Arms steel mag catch, sold separately

Enough S15s for Every Gun, Bag and Range Day.

Once you run S15s, one or three stops being enough. You want one in every 43X or 48 in the house, a spare in the truck and the go-bag, and a stack loaded for the range so you're shooting instead of thumbing rounds.

Pack 6 is ten identical S15 Gen 3 magazines, our largest S15 pack. It's built for shooters who train hard, households with more than one 43X or 48, and instructors who want a matched set.

Features

Why It Holds 15

  • Patented Geometry

    A staggered round stack, protected by US patent, fits 15 rounds in a body built for a slim grip.

  • Steel Body

    Thin steel walls leave room for the 15-round stack and stand up to drops and daily carry.

  • Flush Fit

    Same length as the factory 43X/48 magazine. Nothing hangs below the grip.

  • Ready to Extend

    An easy-remove, impact-resistant base pad swaps for our +2, +5 or +10 extension in minutes.

One Magazine, Four Sizes

Flush at 15. Extend When You Want More.

Carry the S15 flush, or swap the base pad for an extension: 17 with the +2, 20 with the +5, 25 with the +10.

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

Every Pistol Needs a Steel Catch

The S15 is steel and the catch the 43X/48 ships with is polymer, and the two aren't compatible. Each pistol that runs these magazines needs our Standard or Premium steel catch, both made in the USA. It's a one-time install per pistol, and our installation guides walk you through it. Another manufacturer's catch may cause reliability issues.

About the Nitrocarb Finish

QPQ nitrocarburizing adds nitrogen and carbon to the steel's surface in a heated salt bath, forming a hard, even black layer that resists wear and corrosion. Light scuffing of the surface finish is normal and doesn't affect durability.

Questions

S15 Combo Pack 6 FAQ

Does it include a mag catch?

No. Pack 6 is magazines only. Each pistol needs a Shield Arms Standard or Premium steel catch. Setting up more than one 43X or 48? Order one catch per pistol.

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.

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.

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.

Can I get these in nickel?

Pack 6 comes in Nitrocarb. For Silver Nickel or Black Nickel, choose your finish on the single S15 Magazine.

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. Prefer one piece? The S20 holds 20.

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.
