The Glock 43X answered the most requested feature in Glock's history: a single-stack slim pistol with a full-size grip for EDC. Combining the G43's slim 1.1" width with the taller G48 frame, the G43X provides a 10-round magazine in a package that disappears on the hip. The MOS variant adds Glock's Modular Optic System for direct mounting of micro red dot sights.
The aftermarket transformed the G43X with Shield Arms S15 magazines, which fit flush and give 15+1 capacity β making it arguably the best EDC pistol dollar-for-dollar. The combination of Glock reliability, slim profile, and 15-round capacity with the Shield Arms upgrade has made it one of the fastest-growing pistol platforms in the US.
