Summary: The description, specs, pricing, photo and user ratings for the Glock 20 Gen4 pistol.

Manufacturer’s Description

The Glock 20 Gen4 is, like its close relative the Glock 20 Gen3, a semiauto built on a full-size polymer frame and chambered in 10mm. Standard features include three-dot fixed sights and a trigger safety.

In addition, the Gen4 offers several new features, including a multiple backstrap frame with a reduced short-frame trigger mechanism housing. The multiple backstrap system allows the user to change the circumference of the grip to fit their individual hand size.

The grip has three options: a short frame, a medium frame or a large frame. The backstraps are easily changed and secured with a single pin. Note: The Gen4’s grip angle is not changed by backstrap modifications to ensure a shooter doesn’t shoot high or low when modifying the backstrap or when shooting a different Glock pistol.

The 20 Gen4 also sports a Rough Textured Frame (RTF) surface designed to enhance grip traction, and its magazine release catch is now reversible and enlarged. This allows users to switch the catch to the left or right side of the pistol with no additional parts.

Finally, the original recoil spring has been replaced with a dual recoil spring assembly designed to reduce recoil while simultaneously increasing the assembly’s life cycle.

Note: The Glock 20 Gen4 will reportedly be available in the United States in April 2013.
