Compatibility

Fits the Glock® 43X and 48. Runs S-Series and Glock® 15-Round Steel Mags.

The DUAL-FIT replaces the polymer mag catch in the Glock® 43X and 48. It runs Shield Arms S-Series magazines and Glock®'s factory 15-round steel magazines on the same catch. It doesn't fit the single-stack Glock® 43 or double-stack Glocks. Running a Glock® 43? See the Z-Series catches.

What Is the DUAL-FIT Mag Catch?

The DUAL-FIT is a steel magazine catch for the Glock® 43X and 48 that runs two kinds of steel magazine: Shield Arms S-Series mags (S10, S15 and S20) and Glock®'s factory 15-round steel mags. It comes in right-handed and left-handed versions and replaces the factory polymer catch in a one-time install with basic tools. Black nitride finish, made in the USA, lifetime warranty. It takes the place of our Standard and Premium S15 mag catches and is now the steel catch we make for the 43X and 48.

Fits: Glock® 43X and 48, including MOS
Runs: Shield Arms S10, S15, S20 and Glock® factory 15-round steel mags
Versions: right-handed or left-handed shooter
Made in: USA, lifetime warranty

DUAL-FIT

Your S15s and Glock®'s 15s. One Catch.

Steel magazines need a steel catch, and until now that meant picking a side. Our earlier steel catches ran S-Series mags, but not the factory 15-round steel magazines Glock® now sells for the 43X and 48.

The DUAL-FIT runs both. Carry an S15, keep a factory 15-rounder in the bag, or mix them at the range, all on one catch in one pistol. Buying a steel catch for a 43X or 48 today? Start here.

Why a Steel Catch

Steel Mags Run on a Steel Catch

The catch your 43X/48 shipped with is polymer, and it isn't compatible with steel S-Series magazines. The DUAL-FIT is the steel catch they run on, and it handles Glock®'s factory steel 15s too. It's a one-time install, and our installation guides walk you through it. Another manufacturer's catch may cause reliability issues with S-Series mags.

Black Nitride

Replacing the Standard and Premium Catches

The DUAL-FIT takes the place of our Standard and Premium S15 mag catches. If one of those is already running your S-Series mags, it keeps working. Upgrade to the DUAL-FIT when you want to run Glock®'s factory 15-round steel mags in the same pistol.

Questions

DUAL-FIT Mag Catch FAQ

Which pistols does it fit?

The Glock® 43X and 48, including MOS models. For the single-stack Glock® 43, see the Z-Series catches. For the Glock® 19 and 17, see the DS-Series catches.

Which magazines does it run?

Shield Arms S15, S20 and S10 magazines, with or without extensions, and Glock®'s factory 15-round steel magazines for the 43X and 48.

Right-handed or left-handed: which do I order?

Pick the hand you shoot with. The right-handed version puts the button on the left side of the frame, where your right thumb reaches it, the same as a factory 43X or 48. The left-handed version puts it on the right side for your left thumb.

Why do S-Series mags need a steel catch?

S-Series magazines are steel, and the catch the 43X/48 ships with is polymer. The two aren't compatible. A steel catch gives steel magazines reliable lock-up and release over the long run.

I already have a Standard or Premium S15 catch. Do I need this?

Only if you want to run Glock®'s factory 15-round steel magazines. Your current catch keeps running your S-Series mags. The DUAL-FIT runs both.

Will my factory 10-round polymer mags still work?

They'll run, but we don't recommend it for regular use. The DUAL-FIT has rounded edges to keep wear down, but steel on polymer still wears the magazine over time.

Can I get it in a kit?

Yes. The S15 Starter Kit is one S15 and the DUAL-FIT. Combo Pack 1 is three S15s and the catch, and our other catch-included combos add extensions or a Carry Magwell. You only need one catch per pistol.

Can I use another brand's catch with S-Series mags?

We don't recommend it. Another manufacturer's catch may cause reliability issues with S-Series magazines. Ours are the catches we test them with.

How hard is installation?

It's a one-time swap with basic tools and no gunsmithing. Our installation guides walk you through it, and any gunsmith can do it if you'd rather not.

Does it work in a grip-chopped pistol?

Yes. The catch sits in the frame above the grip, so it works in a 43X or 48 converted by our S10 Grip Chop Service. Pistols from the Grip Chop Service and our S10 custom builds now ship with a DUAL-FIT installed.

What's covered by the warranty?

Our lifetime warranty covers defects in materials and workmanship.
