This is a Glock 43X, 48 10-round magazine.
Glock’s newest pistols combine slim and compact size with serious capacity to deliver a high-performance, concealment-ready solution for today’s serious shooter. With more capacity and grip surface than the top-selling Glock 43, and a similar footprint to the classic Glock 19, the 43X and 48 are an exciting addition to practically any arsenal.
Engineered to meet Glock’s perfectionist standards for quality and function, these single-stack 10-round magazines feature durable polymer construction with full-length steel reinforcements, numbered witness holes and impact-resistant polymer followers.
Glock magazines are known for their flawless reliability—thanks in no small part to their heavy-duty internal springs, tough construction and rock-solid polymer followers.
If you’re using your Glock 43X or 48 for concealed carry, remember that it’s important to keep some extra magazines around and rotate your carry kit every 1-3 months in order to maximize service life and ensure superior reliability.
