This review of the Glock 31 in .357 SIG covers its performance, accuracy, and the characteristics of the .357 SIG cartridge. The presenter notes the pistol's accuracy, describing it as a 'tack driver,' and discusses the .357 SIG's velocity and energy compared to 9mm rounds. Potential issues like excessive oil causing combustion compression and visible muzzle flash are also addressed, along with observations on recoil and trigger feel.

Quick Summary

The Glock 31 Gen 4 in .357 SIG is a highly accurate pistol, often described as a 'tack driver.' The .357 SIG cartridge offers superior velocity and energy compared to 9mm +P+ rounds. Shooters may need to adjust their sight picture as this model tends to shoot low, and be mindful of over-oiling, which can cause combustion compression.

Frequently Asked Questions

What are the key characteristics of the .357 SIG cartridge?

The .357 SIG cartridge is known for its high velocity and energy, achieved by necking down a .40 S&W case to accept a 9mm bullet while retaining the .40 S&W powder charge. This results in a fast, powerful round.

How does the Glock 31 Gen 4 perform in terms of accuracy?

The Glock 31 Gen 4 reviewed is described as a 'tack driver,' demonstrating exceptional accuracy with tight groupings. The presenter notes it's capable of impressive precision, even suggesting potential for 100-yard accuracy.

What are common issues or observations when shooting the Glock 31 in .357 SIG?

Some shooters may experience the pistol shooting low, requiring a cover or combat hold. Additionally, over-oiling can lead to combustion compression, and visible muzzle flash is more pronounced than with other common pistol calibers.

How does .357 SIG compare to 9mm +P+ ammunition?

The .357 SIG cartridge significantly outperforms 9mm +P+ in terms of velocity and energy. Claims that 9mm +P+ can match .357 SIG performance are generally inaccurate, as even high-pressure 9mm rounds fall short.
