The GLOCK 22 Gen4 has several new features designed to satisfy the most demanding consumers. Most noticeably, the Gen4 design has a multiple backstrap system that allows the user to change the circumference of the grip to fit their individual hand size. The grip has three options; a short frame version, medium frame or large frame that are easily changed and secured with a single pin.

The magazine release catch of the Gen4 is reversible and enlarged. The reversible magazine catch allow users to switch access of the catch to the left or right side of the pistol with no additional parts. The gun includes THREE MAGAZINES as standard equipment.

Internally, the original recoil spring has been replaced with a dual recoil spring assembly. The dual recoil spring assembly noticeably reduces the recoil while simultaneously increasing the life cycle of the pistol. Additionally, the Gen4 has a new Rough Textured Frame (RTF) surface designed to enhance grip traction and is present on the frame as well as the interchangeable backstraps.
