This article delves into the history, design, features, performance, and applications of the Glock 20, offering a comprehensive overview of this iconic handgun.
A Brief History of the 10mm Auto Cartridge
Before exploring the Glock 20 itself, understanding the 10mm Auto cartridge is crucial. Developed in the early 1980s, the 10mm Auto was initially conceived as a more powerful alternative to the 9mm Parabellum and .45 ACP. It gained initial popularity with the Bren Ten pistol, famously featured in the television series Miami Vice. However, the Bren Ten suffered from production issues and was ultimately discontinued, leaving the 10mm Auto in a precarious position. Despite these initial setbacks, the cartridge persevered, finding favor among those who appreciated its impressive ballistics.
The Birth of the Glock 20
Glock recognized the potential of the 10mm Auto and introduced the Glock 20 in the early 1990s. This pistol provided a reliable and robust platform for the powerful cartridge, addressing many of the issues that plagued earlier 10mm Auto firearms. The Glock 20 quickly gained traction, particularly among law enforcement agencies operating in areas with large predators, such as park rangers and wildlife officers. Its high capacity magazine and significant stopping power made it an ideal choice for defense against both human and animal threats.
Design and Features of the Glock 20
Frame and Slide
The Glock 20 features Glock’s signature polymer frame, which contributes to its relatively light weight despite its large size and powerful chambering. The frame is durable and resistant to corrosion, making it suitable for use in harsh environments. The slide is made from hardened steel and undergoes Glock’s proprietary Tenifer treatment, which further enhances its corrosion resistance and durability. The combination of polymer frame and steel slide results in a robust and reliable firearm.
Barrel and Recoil System
The Glock 20 utilizes a 4.61-inch barrel, which provides a good balance between accuracy and portability. The barrel features Glock’s standard hexagonal rifling, which contributes to consistent accuracy. The recoil system is designed to effectively manage the recoil of the powerful 10mm Auto cartridge. While the recoil is certainly noticeable, it is manageable with proper technique and grip.
Magazine Capacity and Sights
The Glock 20 boasts a standard magazine capacity of 15 rounds, providing ample firepower for a variety of situations. Aftermarket magazines with extended capacities are also available. The pistol comes standard with Glock’s polymer sights, which are durable and functional. Many users opt to replace these with aftermarket sights, such as tritium night sights, for improved visibility in low-light conditions. [See also: Glock Sight Options]
Safe Action System
Like all Glock pistols, the Glock 20 incorporates the Safe Action System, a unique trigger mechanism that provides three independent safeties.

Performance and Ballistics
The 10mm Auto cartridge delivers impressive ballistics, offering a significant increase in power compared to the 9mm Parabellum and .45 ACP.

The Glock 20 can handle a wide range of 10mm Auto ammunition, from lighter loads for target practice to heavier loads for hunting and self-defense.
The recoil of the Glock 20 is a factor to consider. While manageable, it is more pronounced than that of smaller caliber pistols.
