The Glock 37 Gen 4 is a semi-automatic large-frame pistol chambered in .45 GAP. “Gen 4” means it is the fourth generation G37. New features include removable back straps that allow shooters to adjust the grip for size and ease of use. Another new feature, the dual recoil pin, reduces recoil and increases the life cycle of the assembly. The grip texture is more aggressive, so it won’t slip when the shooter’s hands are sweaty or wearing gloves. And, an enlarged magazine release that’s easier to hit.
The GLOCK 37 Gen4, in .45 G.A.P., introduces revolutionary design changes to this quantum leap forward in big-bore technology-our answer to muzzle flip and high velocity recoil. The Modular Back Strap design lets you instantly customize its grip to adapt to an individual shooter's hand size. The surface of the frame employs the new scientifically designed, real-world-tested, Gen4 rough textured technology. Internally, the new GLOCK dual recoil spring assembly substantially increases the life of the system. A reversible enlarged magazine catch, changeable in seconds, accommodates left or right-handed operators. The G37 Gen4 retains the GLOCK accessory rail for your attachments.
