The G43X MOS pairs the Slimline grip profile with a 10+1 capacity in 9mm Luger, and this one is set up with a striker-fired action and Glock's Safe Action system with a trigger safety blade. It is a straightforward configuration for buyers who want the MOS slide format and the familiar G43X footprint in a micro-size pistol.
This example stands out with an upgraded trigger and flat-faced trigger shoe. The trigger weight is listed as 5.5, and the flat-faced shoe provides a distinct interface compared to the standard curved format, while keeping the rest of the pistol's core operating system in the Glock striker-fired pattern.
The slide includes both front and rear cocking serrations, and the MOS optic-cut is currently covered by the factory cover plate secured with two screws. Slide markings include the GLOCK logo, 43X, AUSTRIA, and 9x19, and the barrel hood markings include 9x19, the Glock logo, and AT.
Two factory Slimline magazines are included, and the magazines pictured feature orange followers with witness holes numbered down the rear spine. Glock lists this configuration with the Glock Marksman Barrel (GMB), and the included spare recoil spring assembly provides an additional factory-style wear item on hand.
