Overview of the Glock G20

The first version of the Glock G20 was released in the early 1990s. It was intended to provide increased stopping power with the help of the 10mm Auto round. Over the years, Glock integrated feedback, added modern features, and refined the G20 to increase functionality, turning it into the latest model: Gen5 MOS.

The target can be acquired more easily with reflex sights and optics, making the G20 easier to use. These advantages make the G20 suitable for those who prefer optics rather than traditional iron sights.

GLOCK Marksman Barrel (GMB)

The GMB addition provides better accuracy due to improvement in barrel rifling, resulting in tighter shot grouping within the same spot.

Ambidextrous Controls

The slide stop lever, which is usable for both sides, has been placed to accommodate left-handed users. This change enhances ease of use.
Enhanced Frame Design

The absence of finger grooves gives a more ergonomic hold with a better grip for a greater range of hand sizes. Moreover, the flared mag-well enables faster and more seamless magazine changes. ​
