Details 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.
