The Glock 43X Just Received A Big Update
Glock has updated the MOS footprint on the 43X, particularly FDE/Coyote models, replacing bosses with screw posts for direct mounting of popular optics like Holosun 507K and EPS Carry. This new design offers improved optic stability and thread engagement compared to the original MOS system. The update simplifies optic installation, eliminating the need for milling or adapter plates for compatible red dots.
