This video compares supersonic and subsonic 9mm ammunition when fired from a suppressed Kriss Vector. Subsonic rounds are highlighted as crucial for eliminating the sonic boom 'crack' and achieving maximum quietness with suppressors. A live-fire demonstration visually and audibly contrasts the two ammo types.

Quick Summary

Subsonic 9mm ammunition is quieter with suppressors because it travels below the speed of sound, eliminating the sonic boom 'crack'. Supersonic ammo breaks the sound barrier, creating noise. A Kriss Vector test shows the audible difference.

Frequently Asked Questions

What makes subsonic 9mm ammo quieter when suppressed?

Subsonic 9mm ammo travels below the speed of sound, preventing the 'crack' of a sonic boom. This, combined with a suppressor, significantly reduces the overall noise signature compared to supersonic rounds.

How does subsonic ammo differ from supersonic ammo?

Supersonic ammo exceeds the speed of sound, creating a sonic boom. Subsonic ammo travels slower than the speed of sound, eliminating this boom and making it ideal for suppressed firearms where noise reduction is paramount.

What firearm was used in the Kriss Vector 9mm ammo test?

The video features a Kriss Vector chambered in 9mm, equipped with a suppressor and optic. This platform was used to demonstrate the audible differences between various 9mm ammunition types.
