Overview of the Glock 31 Gen 4

The Glock 31 Gen 4 is a full-size, semi-automatic pistol with a standard 15-round magazine capacity (depending on state regulations).

Key Features of the Glock 31 Gen 4

1. .357 SIG Chambering

One of the primary features of the Glock 31 Gen 4 is its .357 SIG chambering, which provides higher velocity and increased energy compared to standard 9mm rounds. This caliber is particularly effective for self-defense, as it combines the flat trajectory of a 9mm with the stopping power of a .40 caliber, offering users a balance of speed, accuracy, and power.

2. Modular Backstrap System

The Gen 4 model of the Glock 31 includes a modular backstrap system, allowing users to adjust the grip size to fit their hand comfortably. This customization improves grip comfort and control, particularly during extended shooting sessions, which is essential for managing the power of the .357 SIG round.

3. Dual Recoil Spring Assembly

To handle the .357 SIG’s increased power, the Glock 31 Gen 4 features a dual recoil spring assembly. This system reduces felt recoil, making the pistol easier to control and improving the lifespan of the recoil spring. The result is a smoother shooting experience, even with the potent .357 SIG cartridge.

4. Safe Action Trigger System

Like all Glock models, the Glock 31 Gen 4 includes Glock’s Safe Action Trigger System, which provides a consistent trigger pull from the first round to the last. This system enhances safety by incorporating three automatic safeties that prevent accidental discharge, ensuring the pistol only fires when the trigger is intentionally pulled.

5. Accessory Rail

The Glock 31 Gen 4 comes with an accessory rail under the barrel, allowing users to attach accessories like lights or lasers for improved performance in low-light situations. This feature is particularly useful for those using the Glock 31 for home defense or duty applications.
