Glock 43X MOS Holsters

Deluxe Holsters for Your Glock 43X MOS

The Glock 43X MOS builds on the slim, carry-friendly Glock 43X platform by adding optic-ready capability. Its Modular Optic System allows shooters to mount a compatible micro red dot while maintaining the narrow frame and controllable grip that make the 43X popular for concealed carry. That added optic capability changes what a holster needs to support. A proper Glock 43X MOS holster must provide secure firearm retention while keeping the mounted optic protected, accessible, and unobstructed during the draw.

At Rounded Gear, every Glock 43X MOS holster is manufactured with firearm-specific and optic-ready fitment in mind. Built entirely in-house at our Jacksonville, Florida facility, our holsters are formed using CNC-machined aluminum molds engineered around the Glock 43X MOS platform. This process supports consistent retention, reliable positioning, and a smooth draw path for optic-equipped carry. Whether you prefer appendix, strong-side, or OWB carry, our holsters are built for dependable real-world performance.
