The Glock 37 is a tough, resilient weapon that uses a .45 GAP cartridge. This is the 4th generation of model 37 and includes common Gen 4 features like removable back straps, redesigned finger grooves, and more aggressive texture for better customization of the grip, the dual-recoil spring for reduced recoil, and an enlarged magazine catch, suitable for both left-handers and right-handers. The double-action trigger has a three-point safe-action mechanism making the gun as safe as it’s possible. The standard capacity of the magazine is 10 rounds, with a possible +1 extension, and it is reversible. The gun is very handy and can be equipped with a lot of additional accessories (holsters, parts, lasers, sights, slide-back platers, etc.). The Glock 37 comes with standard Glock sights (a front white dot and a rear U-shaped mark) but they can be upgraded with a variety of different new and improved sights, like night sights and others. The gun stays accurate enough even during rapid fire.
