About the Glock 20 Gen4
The Glock 20 is a full-size, striker-fired pistol chambered in the powerful 10mm Auto cartridge, introduced in 1990. It pairs Glock's proven Safe Action system and polymer frame with a large-frame slide sized to handle the high-energy 10mm round, making it a favorite for hunting, backcountry defense against large animals, and shooters who want maximum power in a service-size handgun. The Gen4 adds a reversible magazine catch, the Modular Backstrap System, and a rough-textured frame.
The 10mm Auto Glock 20 found a strong following among outdoorsmen and hunters as a lightweight alternative to a revolver for defense against bears and other large game.
