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.
