This guide details the process of mounting a Holosun 507K optic onto a Glock 43X MOS pistol. It emphasizes the necessity of slide machining due to the 507K's Modified RMSc footprint, which differs from the standard MOS system. The video, presented by Lenny Magill of GlockStore, highlights how milling the slide allows for a lower optic height, improving co-witness with iron sights and a more natural point of aim. Proper safety precautions are stressed throughout the installation process.
