Frequently Asked Questions

What makes the .357 SIG cartridge powerful?

The .357 SIG achieves its power through a combination of high velocity, often exceeding 2000 feet per second with specialized loads, and a design that allows for a significant powder charge within its case. This results in excellent penetration capabilities and significant energy transfer.

How does the .357 SIG compare to the 10mm and 9mm?

The .357 SIG offers more power and penetration than a 9mm, often in a similar-sized firearm, with less recoil than a 10mm. While the 10mm is generally considered the most powerful semi-automatic round, the .357 SIG provides a potent balance of power, manageable recoil, and effective barrier penetration.

What are the advantages of .357 SIG ammunition for self-defense?

For self-defense, .357 SIG ammunition, particularly specialized loads like Underwood's Extreme Defender, offers superior penetration through barriers like glass and doors. It's designed to stop a threat effectively with a single shot, while also aiming to limit over-penetration to protect bystanders.

Why was the .357 SIG developed?

The .357 SIG was developed by SIG Sauer and Federal for law enforcement agencies seeking a high-performance handgun round. The goal was to provide a cartridge with significant stopping power and barrier penetration capabilities, comparable to revolvers like the .357 Magnum, but in a semi-automatic platform.
