The Glock 40 Gen 4 in MOS Configuration is the biggest Glock’s offering and is chambered in powerful 10mm rounds. It combines a long slide and a 6-inch barrel, called “the hunting length barrel”, for an improved velocity of 1300+ feet per second. This gun is perfect for an outdoor person, hunter, or sport shooter. The magazine capacity is 15 rounds, and the pistol comes with 3 magazines (one inserted and two in addition). The grip is massive, customizable, includes finger grooves, and has a square textured pattern. Unlike some other Glock handguns, it doesn’t have an extended slide stop. The MOS system (Modular Optic System) is the latest addition to the Glock family. Mounting a reflex sight on the gun’s slide is super easy thanks to the MOS Configuration and it doesn’t require a new slide or different mounting equipment. The pistol is just a little over 32 ounces without a magazine and that is surprisingly light considering its size. It might feel a bit unbalanced and front-heavy when it’s empty, but after you insert the magazine, it starts to balance out. The trigger is long, soft on touch, and without the serrations, unlike most other Glock’s handguns. The red dots on the handgun help shooters achieve 10-20% better speed or accuracy. Like all Glock pistols, it is based on the same Glock Safe Action with three internal safeties (a trigger block safety, a firing pin safety, and a drop safety) that operate automatically. The Tenifer metal finish used on Glock slides and barrels is amazingly resistant to corrosion and other damaging conditions, and the well-known polymer frame contributes to recoil reduction. Muzzle rise is reduced thanks to the low bore axis. The Glock 40 is reliable, easy to operate and maintain, and a perfect choice for those who love hunting games, protection against four-legged predators, and home defense.
