Glock 43X MOS Slimline 9mm Compact Pistol – Optic-Ready, 15+1 Capacity

The factory MOS slide cut accepts RMSc-footprint micro red-dot optics, allowing a low-profile sight installation that aligns perfectly with the Slimline slide width.
Three steel S15 magazines boost onboard capacity to 15+1 rounds while maintaining the 43X’s slim grip circumference, eliminating the need for extended baseplates.
The 3.41-inch Glock Marksman Barrel features enhanced polygonal rifling for consistent shot-to-shot accuracy and easier cleaning. A durable nDLC black finish protects the slide, which also wears forward and rear serrations for confident manipulation.
A glass-fiber-reinforced polymer frame keeps weight down and offers a reversible magazine release for left- or right-handed shooters. Glock’s Safe-Action system with trigger safety tab provides the same familiar, consistent pull found across the lineup.
Standard polymer iron sights—a white-dot front and white “U”-notch rear—give a clear sight picture out of the box, and the slim, compact dimensions make the 43X MOS easy to conceal or holster.
