The G43X MOS pairs Glock's Slimline profile with the Modular Optic System cut sized for RMSc-type micro-optics, using the direct-mount Slimline pattern with no adapter plates. The slide incorporates front and rear serrations and a factory optic cover plate when an optic is not installed.
Its 3.41 in Glock Marksman Barrel (GMB) and fixed sights with a white-dot front and white-outline rear provide a clear sight picture. The black nDLC slide finish offers durability, while the polymer frame features a textured grip with an integrated beavertail for consistent control.
The pistol uses Glock's striker-fired Safe Action system and a reversible magazine release. A single-slot Slimline accessory rail on the dustcover supports compatible compact accessories.
Capacity is listed at 15+1 with the included metal-bodied Slimline magazines compatible with the Glock 43X/48 format. These magazines are aftermarket and non-factory type, as noted.
This example is marked 'US' on the barrel hood and 'MADE IN USA - GLOCK, INC., SMYRNA, GA' on the frame, with matching serial numbers on the frame, slide, and barrel.
