The Glock 20 is a renowned 10mm semi-automatic handgun noted for its power, reliability, and practicality. As a standard-bearer in its class, it offers impressive performance with controllable recoil, making follow-up shots quick and accurate. The Gen 3 model, in particular, has been praised for its durability and functional design, though its original large grip size was adjusted in the Gen 3 SF models and carried forward in the Gen 4 models with additional backstraps for customization. The Glock 20 features a 15-round magazine, making it superior to many large magnum revolvers in terms of capacity and ease of ammunition changes. It also includes an accessory rail for mounting a weapon light, enhancing its versatility for low-light situations. The factory plastic sights are easily replaceable with aftermarket options. The Glock 20 remains a solid choice for those needing a reliable and powerful handgun for defensive purposes or hunting, with the familiarity of Glock controls aiding in a smooth transition from other Glock models.
