Best Compact 9mm Pistol Ammo?! HST vs Gold Dot vs Critical Duty

Published on April 10, 2019
Duration: 8:29

This expert-level review from 1ShotTV compares five popular 9mm self-defense ammunition types fired from a Sig Sauer P320 Compact, simulating compact pistol performance. The test utilizes a ballistic gel block with an FBI heavy clothing kit to assess penetration and expansion. Key findings highlight how barrel length influences ammunition performance, with some rounds exhibiting unexpected penetration and expansion characteristics compared to longer barrel tests. The presenter, demonstrating significant expertise in ballistics and firearm testing, provides detailed observations on each ammunition's performance.

Quick Summary

Compact 9mm pistol barrels typically produce lower velocities, impacting ammunition performance. In ballistic gel tests with an FBI clothing kit, Federal HST and Speer Gold Dot showed increased penetration from a Sig P320 Compact, while Hornady Critical Defense performed as expected with good expansion and penetration.

Frequently Asked Questions

How does barrel length affect 9mm self-defense ammunition performance?

Shorter barrels on compact pistols typically result in lower muzzle velocity. This reduced velocity can lead to less efficient bullet expansion, potentially causing increased penetration through tissue or barriers, as observed in tests with Federal HST and Speer Gold Dot.

Which 9mm ammunition performed best in the compact pistol ballistic gel test?

All tested rounds performed well, but the 115gr Hornady Critical Defense showed good expansion and penetration for its class. Federal HST and Speer Gold Dot exhibited surprising penetration from the compact barrel, while Fort Scott TUI created exceptionally large wound cavities.

What is the FBI heavy clothing kit used for in ballistic testing?

The FBI heavy clothing kit, consisting of layers like denim, heavy fleece, and t-shirts, simulates common clothing worn by individuals. It's used in ballistic gel tests to assess how ammunition performs when encountering and penetrating these materials before reaching the gel medium.

Are Federal HST and Speer Gold Dot suitable for compact 9mm pistols?

Yes, Federal HST and Speer Gold Dot are generally considered excellent self-defense rounds. However, this test showed they may penetrate deeper than expected from compact pistols due to lower velocities, which is a factor to consider in specific defensive scenarios.
