9mm Subsonic Showdown: Freedom Munitions

Published on October 5, 2017
Duration: 4:53

This review by Kit Badger tests three 9mm subsonic offerings from Freedom Munitions: 147gr Remanufactured, 147gr Hush, and 165gr Hush. The primary finding was a consistent failure to cycle reliably in a Glock 17 with a Liberty Mystic suppressor, making them impractical for use. The reviewer notes that other ammunition brands cycled without issue, indicating a compatibility problem with the tested Freedom Munitions products.

Quick Summary

Subsonic ammunition is crucial for suppressor effectiveness, preventing the supersonic crack. Typically, 147-grain 9mm loads around 900 fps are subsonic, while supersonic rounds exceed 1100 fps. However, Freedom Munitions' 147gr and 165gr Hush 9mm loads failed to cycle reliably in a Glock 17 with a Liberty Mystic suppressor.

Frequently Asked Questions

What is the purpose of subsonic ammunition when using a suppressor?

Subsonic ammunition is used with suppressors to avoid the 'crack' of a supersonic bullet breaking the sound barrier. By staying below the speed of sound (typically under 1100 feet per second for 9mm), the sound signature is significantly reduced, enhancing the effectiveness of the suppressor.

Which Freedom Munitions 9mm subsonic loads were tested by Kit Badger?

Kit Badger tested three Freedom Munitions 9mm subsonic loads: 147-grain Remanufactured, 147-grain Hush, and 165-grain Hush. The reviewer aimed to find the quietest option for suppressor use.

Did the Freedom Munitions 9mm subsonic ammunition cycle reliably in the test?

No, all three tested Freedom Munitions 9mm subsonic loads (147gr Remanufactured, 147gr Hush, 165gr Hush) failed to cycle reliably in the reviewer's Glock 17 with a Liberty Mystic suppressor, experiencing frequent malfunctions.

What was the conclusion regarding Freedom Munitions subsonic 9mm ammo compatibility?

The primary conclusion was that the tested Freedom Munitions subsonic 9mm ammunition was not compatible with the reviewer's specific firearm and suppressor setup due to consistent cycling failures. Other brands of subsonic ammo performed reliably.
