Glock 31 Gen 4

Glock 31 4th Generation

The Glock 31 Gen 4 is a semi-automatic large-frame pistol chambered in .357 SIG. “Gen 4” means it is the fourth generation Glock 31. 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.

Otherwise it has standard Glock features such as a polymer grip that’s very lightweight at 2.1 pounds loaded. On the front of the grip are finger grooves for a solid hold. Its double-action trigger is also “safe-action” meaning the safety is on the trigger rather than the side. The only way a round can fire is if the shooter pulls the trigger because its internal design won’t allow the firing pin to punch forward any other way. This prevents accidental discharges if the pistol is dropped.

The round .357 SIG is not much different from .40 S&W except it can travel a greater distance and it costs more.

Glocks have a simple, dependable and easy-to-use design, which is why the New Jersey police use the G31 their service weapon. Glock recommends the G31 Gen 4 for opened carry and long range shooting.
