Glock is finally releasing an OEM 15-round magazine for the G43X and G48 (Part No: GL79269). This is a huge shift, as these models were strictly 10-round from the factory since 2019.
What We Know About the New OEM 15-Rounder:
- Release Timeline: Shipping to major distributors (like Lipsey’s) is expected to begin in mid-April 2026. Some retailers have already opened pre-orders.
- Construction: Unlike the polymer-coated 10-rounders, these appear to use an all-metal body (similar to how Shield Arms designs theirs) to fit the extra rounds into the same slim footprint.
- Magazine Catch: The best news for you is that since it's an official Glock part, it is designed to work with your stock polymer magazine release. You won't have to swap to a steel catch like you do with the Shield Arms S15.
- Compatibility: It is a flush-fit for all G43X and G48 variants, including the MOS models.
