Glock Magazine Catch Reversible G43X G48 9mm

The Glock magazine catch reversible G43X G48 9mm is the factory OEM solution for Slimline owners returning to a factory setup — or anyone who needs a verified spare before heading to the range.

For years, the G43X and G48 topped out at 10 rounds with the factory magazine. Because of that capacity ceiling, many owners swapped to Shield Arms S15 magazines, which required an aftermarket steel magazine catch to function reliably. That aftermarket catch worked well for the S15 — but Glock has since released their own factory 15-round Slimline magazine (GL79269), and that new OEM magazine is not always compatible with the Shield Arms steel catch already installed in the gun. As a result, owners upgrading to the factory 15-rounder often need to return to the OEM polymer catch to run the new magazine reliably. This part is exactly that component.

Why This Product Stands Out — Glock Magazine Catch Reversible G43X G48 9mm

Beyond the 15-round upgrade path, this catch handles two other common scenarios well. First, it serves as a direct factory replacement for a damaged or worn catch — which happens more often than it should, because many owners attempt to swap sides using a flathead screwdriver and strip the part in the process. Second, the reversible design allows right- or left-hand configuration without sourcing a separate component, making it a practical pick for southpaw G43X and G48 owners.

Because it’s a Glock-manufactured OEM part, it installs without modification and functions identically to the component that shipped in the pistol. Furthermore, the price point makes it a no-brainer to keep one in a parts kit alongside any G43X or G48 in inventory.
