The Glock 43X and Glock 48 models feature a micro-optic-ready factory-milled slide and a non-standard accessory rail. With a Modular Optic System (MOS) footprint, the Slimline MOS models require specific micro-reflex optics such as the Shield RMSc. The versatility of the Slimline MOS models give them the adaptability for concealed carry, target shooting, law enforcement, and competition shooting.
