This review by hickok45 compares the Glock 20 Gen 3 and Gen 4 in 10mm Auto. While the Gen 4 features ergonomic upgrades like interchangeable backstraps and a revised grip texture, the primary internal change is a dual recoil spring assembly intended to reduce felt recoil. Testing with both standard and heavy 10mm loads revealed that the recoil reduction in the Gen 4 is subtle, with external factors like aftermarket grip enhancements often having a more noticeable impact on perceived recoil than the internal spring system difference.
The Glock 20 in 10mm Auto is a powerful full-size pistol suitable for self-defense, hunting, and range use. It offers significant ballistic advantages over common calibers like 9mm and .45 ACP, matching .357 Magnum performance with higher capacity. The video details its size, ergonomics, history, and field stripping.
