The Night Fision Optics Ready Stealth night sights for Glock 43X MOS in the .220-.227 blade height are made to sit under a pistol red dot instead of fighting it (Night Fision part no. GLK003220227ZXZX). This is Night Fision’s Optics Ready Stealth series, a tritium sight designed to be paired with a slide-mounted optic for roughly a lower 1/3 co-witness. The .220-.227 height lines up with a plate-mounted Holosun EPS Carry on an MOS-cut gun, and the steel construction is finished in black nitride. For a concealed-carry Glock that wears a micro red dot, it keeps a usable backup sight picture without adding bulk.

Key Specifications

• Fit is the Glock 43X MOS, the Version 1 model with the factory RMSc cut that Night Fision lists in its Glock 42, 43 and 43X MOS group.
• Front blade height is .220 to .227 inch, the size Night Fision pairs with a plate-mounted Holosun EPS Carry on an MOS-cut gun.
• The height gives about a lower 1/3 co-witness with the optic, so the irons sit low in the window.
• The sights use Swiss tritium vials behind a domed lens, which Night Fision says gives a sharper, brighter sight picture.
• Each sight is CNC machined from steel with a black nitride coating for wear and corrosion resistance.
• A patented injection-molded sleeve holds the tritium and forms the ring Night Fision calls The Perfect Dot.
• Installation is gunsmith recommended, and Night Fision publishes an install guide.
