The Glock G20 Gen5 MOS pistol in 10mm with a 4.6-inch barrel and 15+1 capacity (brand part no. UA205S203MOS) pairs the hard-hitting 10mm chambering with Glock’s Modular Optic System for direct red dot mounting. Glock finishes the polymer-framed pistol in black matte, and the Safe Action system layers three separate automatic safeties for reliable, drop-safe carry. White-dot front and white-outline rear sights come standard, and the kit includes one adapter plate along with the Glock Marksman Barrel and a flared magwell for faster reloads. Three 15-round magazines ship with the pistol. Among optic-ready 10mm semi-auto handguns, this G20 Gen5 MOS configuration favors hunting and outdoor defense shooters who want red dot compatibility.
