The G20 Gen5 MOS is the first factory 10mm Glock to benefit from the Gen5 updates, including the flared mag-well for faster reloads and the ambidextrous slide-stop lever for left- or right-hand manipulation.
The Glock Marksman Barrel features enhanced polygonal rifling and a target-style crown, contributing to the pistol’s well-known durability and consistent accuracy in the stout 10mm chambering.
Front and rear slide serrations, combined with the MOS optics cut, support confident manipulations and ready compatibility with today’s micro-red-dot sights. The included adapter plates cover the major footprints so you can mount your preferred optic without extra parts.
This pistol carries Glock’s nDLC finish, offering increased hardness and corrosion resistance over earlier coatings. The serial prefix “CBPS” places production in the 2024-25 block, aligning with the most recent Gen5 manufacturing updates.
An aftermarket wrap-around grip tape has been professionally applied, giving the shooter a more aggressive texture while preserving the pistol’s original lines and modular-backstrap capability.
