The Glock 43X in this configuration is a 9mm Luger single-stack-width pistol built with an optic-ready, serrated slide, giving shooters the 43X’s slim, carry-friendly dimensions with the option to run a red dot (brand part no. UX4350204NR15ORMAKO). Glock ships it with three optic mounting plates, so a range of compatible red dots can be mounted directly to the slide without an aftermarket adapter. Three passive internal safeties disengage sequentially as the trigger is pulled and automatically re-engage on release, and the extractor doubles as both a visual and physical loaded chamber indicator. It ships complete with two magazines, a magazine loader, a cleaning kit, a pistol case, and a gun lock, giving a shooter everything needed to start carrying immediately.
