The G43X MOS integrates Glock's Slimline MOS system with an RMSc-pattern micro-optic interface and a factory-installed cover plate, giving the slide a clean, ready-to-configure footprint. Front and rear slide serrations provide positive purchase, and the black slide finish complements the durable polymer frame.
Its 3.41 in Glock Marksman Barrel supports the 9mm Luger chambering, and the model's 10+1 capacity aligns with the Slimline magazine design. The striker-fired action uses Glock's Safe Action System, and the reversible magazine catch supports different shooter preferences.
The frame features microtextured grip surfaces and the single-slot Glock Slim Mounting Rail on the dust cover. Standard Glock polymer sights include a white-dot front and white U-notch rear for a familiar sight picture.
This example includes an installed aftermarket flared magwell funnel, blending smoothly with the Slimline grip for a finished appearance. Left-side slide stop lever, Slimline slide markings, and matching serial numbers on the barrel, slide, and frame round out the details.
