Fits the Glock® 19. The Steel Catch Is Included.

The DS18 fits the Glock® 19, Gen 3 through Gen 6. It won't fit a Glock® 17-length grip frame, including the 17, 34, 45, 47 and 19X; for those, choose DS20 Combo 1. It's a steel magazine, so the combo includes our DS-Series Standard steel mag catch in place of the factory polymer catch. Choose Gen 3 or Gen 4/5/6 to match your pistol.

Stippled or modified grips: DS-Series magazines may fit tight in a stippled or modified grip. We know of no reliability issues, but in those pistols the magazine may not drop free.

What Is the DS18 Combo 1?

DS18 Combo 1 is a full Glock® 19 magazine setup: three Shield Arms DS18 18-round steel magazines and the DS-Series Standard steel mag catch they run on, in a Gen 3 or Gen 4/5/6 version. Each DS18 holds three more rounds than the 15-round factory magazine with only a minimal increase in overall length, and has an over-insertion stop stamped into the steel body. Three magazines give you 54 rounds. Made in the USA, with a lifetime warranty and Spring for Life.

  • In the combo: (3) DS18 magazines, (1) DS-Series steel mag catch
  • Fits: Glock® 19, Gen 3–6
  • Capacity: 18 rounds per magazine, 54 total
  • Catch: Gen 3 or Gen 4/5/6, your choice
Carry + Spares

Eighteen in the Gun. Two Reloads on the Belt.

The DS18 fits 18 rounds of 9mm in a magazine sized for the Glock® 19. Steel walls are thinner than a polymer mag, and that's where the extra three rounds come from.

Combo 1 gives you three identical DS18s, one for the pistol and two for reloads, plus the steel catch they all run on. Swap the catch once and every magazine in the box is ready to go.

In the Combo

A Complete Glock® 19 Mag Setup

  • Three DS18 Mags

    18 rounds each in a steel body, three more than the factory 15, with only a minimal increase in length.

  • DS-Series Steel Catch

    The DS-Series Standard catch in black nitride, Gen 3 or Gen 4/5/6. Ambidextrous, runs the DS18 and DS20. Made in the USA.

  • Stamped Over-Insertion Stop

    Pressed into the steel to set seating depth on every reload. Glock® builds one into its factory mags; most aftermarket mags leave it out.

  • Same Feel Every Reload

    Three identical magazines, so your carry mag and your reloads seat and lock the same way.

DS18 vs. Factory

Three More Rounds in a Glock® 19.

The DS18 holds 18 against the factory 15 with only a minimal increase in length. Want a longer reload? The DS20 also runs in a Glock® 19, holding 20 with the base extending below the grip.

Both run on the same DS-Series catch. Capacity laws vary by state and city. Check yours before you buy.

Why a Steel Catch

Steel Mags Run on a Steel Catch

The DS18 is steel and the catch your Glock® 19 shipped with is polymer. We believe the best path to long-term reliability is steel on steel or polymer on polymer, so this combo includes our DS-Series Standard steel catch. Pick Gen 3 for a Gen 3 Glock® 19, or Gen 4/5/6 for a Gen 4, 5 or 6. It's a one-time install, and our installation guides walk you through it.

Install Guide DS-Series Catch
Choose Your Catch

Gen 3 or Gen 4/5/6?

Glock® changed the mag catch between generations, so pick the catch that matches your pistol, not the magazine. Gen 4, Gen 5 and Gen 6 Glocks are marked with their generation on the slide. A Glock® 19 with no marking is almost always a Gen 3.

Questions

DS18 Combo 1 FAQ

Which pistols does it fit?

The Glock® 19, Gen 3 through Gen 6. For the Glock® 43X and 48, see the S-Series. For the Glock® 43, see the Z-Series.

Will it work in a Glock® 17 or 45?

No. The DS18 is sized for the Glock® 19 grip. For the Glock® 17, 34, 45, 47 or 19X, use DS20 Combo 1.

Do I need anything else?

No. The combo includes the steel catch all three magazines run on. Choose Gen 3 or Gen 4/5/6 to match your pistol, install the catch and load up.

Which catch do I choose?

Gen 3 for a Gen 3 Glock® 19. Gen 4/5/6 for a Gen 4, 5 or 6. Still unsure? Contact our support team before you order.

How hard is the catch install?

Swapping a Glock® mag catch is a common at-home job with basic tools. Our installation guides walk you through it.

Will it drop free in a stippled grip?

It may not. DS-Series magazines can fit tight in a stippled or modified grip. We know of no reliability issues, but in those pistols the magazine may not drop free when you press the catch.

Will my factory polymer mags still work?

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

Combo 1 or the Starter Kit?

The DS18 Starter Kit is one DS18 and the catch, a way to try it. Combo 1 is three DS18s and the catch, enough for a full setup with spares.

Can I run a DS20 in my Glock® 19 too?

Yes. The DS20 runs on the same catch and holds 20, with the base extending below the grip, so it works as a longer reload.

Are DS18 extensions available?

Not yet. We're engineering extensions built for DS-Series magazines. They'll be sold individually and in DS-Series combos.

What's covered?

A lifetime warranty against defects in materials and workmanship, plus Spring for Life: free replacement springs for as long as you own your magazines.
