Sig 365 Ammunition, Should You Care?

Published on March 20, 2024
Duration: 19:56

This video investigates the performance differences of ammunition, specifically Sig Sauer's 365 ammunition, when fired from short-barreled micro-compact pistols compared to standard 4-inch barrels. It demonstrates that barrel length significantly impacts projectile velocity and, consequently, ammunition performance, particularly for defensive hollow-point rounds. The testing highlights the importance of understanding how your chosen ammunition will perform from your specific firearm's barrel length.

Quick Summary

Ammunition designed for standard 4-inch barrels may not achieve sufficient velocity in shorter 3-inch barrels, impacting the effectiveness of defensive rounds like hollow points. Sig Sauer's 365 ammunition is optimized for these shorter barrels, maintaining consistent velocity and performance.

Frequently Asked Questions

Why is ammunition performance important for short-barreled pistols like the Sig P365?

Ammunition designed for standard 4-inch barrels may not achieve sufficient velocity in shorter 3-inch barrels. This can impact the effectiveness of defensive rounds, such as hollow points, which rely on velocity to expand properly.

Does Sig Sauer's 365 ammunition perform differently in short barrels?

Sig Sauer developed its 365 ammunition specifically for shorter barrels found in micro-compact pistols. Testing shows it maintains consistent velocity and performance, making it a reliable choice for these firearms.

Can I use regular 9mm ammunition in my Sig P365?

You can, but standard 9mm ammunition intended for longer barrels might not perform optimally. You may experience lower velocities, which could affect the terminal ballistics of defensive rounds. It's recommended to test your chosen ammo in your specific firearm.

How much does barrel length affect 9mm ammunition velocity?

Even a difference of about one inch in barrel length, such as from a 3-inch to a 4-inch barrel, can result in a measurable decrease in muzzle velocity. This reduction can be critical for ammunition designed to expand upon impact.
