Glock 43X/48 Magazine Features The Glock 43X/48 Magazine brings a 15-round capacity to a platform that was previously limited to a 10-round polymer magazine giving shooters significantly more ammunition on tap without switching pistols. Built with a metal double stack design this magazine represents a departure from Glock s original slimline polymer magazines while still maintaining the pistol s narrow grip profile. A radius cut in the magazine catch recess allows the magazine to work with the pistol s standard magazine catch meaning no modification to the factory magazine release is needed. This detail matters for shooters who want the added capacity without compromising the reliability of their existing setup. The magazine retains the same overall length as the original 43X/48 magazine with only a slightly longer baseplate extending below the grip to aid in recoil control during rapid strings of fire. That small extension gives the shooting hand a touch more purchase for retention and control without meaningfully changing how the pistol conceals. As with all Glock magazines a break-in period may be required before the final round loads easily and Glock recommends loading all but the last round and letting the magazine sit for a few days to help the spring compress properly. This factory 15-round magazine gives 43X and 48 owners a straightforward way to boost their pistol s on-board capacity in 9mm.
