This video provides an expert-level review of 9mm subsonic ammunition from Freedom Munitions, tested on a Glock 17 with a Liberty Mystic suppressor. The reviewer, Ivan from Kit Badger, found that the Freedom Munitions 147gr and 165gr HUSH loads, as well as their 147gr remanufactured offering, experienced significant cycling failures. In contrast, HSM 147gr subsonic ammunition demonstrated much better reliability in the same setup, highlighting potential compatibility issues with specific ammunition and firearm/suppressor combinations.

Quick Summary

HSM 147gr 9mm subsonic ammunition proved most reliable in a Glock 17 with a Liberty Mystic suppressor, unlike Freedom Munitions HUSH 147gr and 165gr loads which suffered frequent cycling failures. Subsonic ammo is key for suppressors to avoid the sonic crack.

Frequently Asked Questions

Which 9mm subsonic ammunition performed best in the Kit Badger test?

In the Kit Badger test featuring a Glock 17 and Liberty Mystic suppressor, HSM 147gr 9mm subsonic ammunition demonstrated the best reliability, cycling consistently with only minor issues. Freedom Munitions' 147gr and 165gr HUSH loads experienced significant cycling failures.

Why is subsonic ammunition important when using a suppressor?

Subsonic ammunition travels below the speed of sound (around 1125 fps), eliminating the loud 'crack' associated with supersonic bullets. This makes it crucial for maximizing the noise reduction benefits of a suppressor, creating a much quieter shooting experience.

What issues were encountered with Freedom Munitions HUSH 9mm ammo?

During testing on a Glock 17 with a Liberty Mystic suppressor, Freedom Munitions HUSH 9mm ammunition in both 147gr and 165gr weights experienced frequent malfunctions, including double feeds and failures to cycle, rendering it unreliable in that specific setup.

How does 147gr subsonic 9mm compare to 115gr supersonic 9mm?

147gr subsonic 9mm travels slower (around 900 fps) and is quieter, especially suppressed. 115gr supersonic 9mm travels faster (1100+ fps) and produces a distinct sonic crack. While 147gr is often preferred for suppressed shooting, reliability can vary significantly between brands and firearm setups.
