The G43X MOS is part of Glock's Slimline series, offering a compact 9mm package with a 10+1 capacity and a textured Slimline grip with a built-in beavertail. It uses Glock's Safe Action system with a striker-fired action and a reversible magazine release for adaptable handling.
The 3.41 in steel Glock Marksman Barrel features hexagonal rifling and a right-hand 1:9.84 in twist for consistent bullet stability. Fixed sights include a white-dot front and a standard factory rear, providing a clear, durable sight picture.
The slide is cut for the Slimline MOS pattern and accepts RMSc-footprint micro-reflex optics. Front and rear slide serrations offer positive purchase, and the frame includes a single-slot Slimline accessory rail for compact lights compatible with this pattern.
Finished in Flat Dark Earth on both the slide and frame, this example also carries useful details for documentation: a P mark on the slide, a D mark on the frame, and matching serial numbers on the barrel, slide, and frame. The frame is U.S.-marked with "MADE IN USA GLOCK, INC., SMYRNA, GA."
