Glock G20 Gen5 10mm Auto 10rd Black Polymer Frame Pistol

The Glock G20 Gen5 delivers the raw power of 10mm Auto ammunition in a refined, reliable platform built for serious applications. This full-size pistol combines proven Glock engineering with fifth-generation improvements to handle one of the most potent service cartridges available.

What Makes This Different

The Gen5 platform incorporates the Glock Marksman Barrel (GMB) with enhanced polygonal rifling that improves accuracy over previous generations by up to 10%. The ambidextrous slide stop lever accommodates both left and right-handed shooters, while the flared magwell speeds reloads under pressure. Unlike earlier generations, the Gen5 eliminates finger grooves for a more universal grip fit and features a reversible enlarged magazine catch for enhanced control.

Hunters appreciate the flat trajectory and energy retention for medium game at extended ranges. The pistol maintains Glock's reputation for functioning in adverse conditions, cycling reliably through temperature extremes and contamination that would compromise lesser firearms.
