5.7x28mm "Normal VS Suppressed VS Subsonic Ammo"

Published on June 18, 2025
Duration: 0:47

This video compares the sound and performance of 5.7x28mm ammunition fired unsuppressed, suppressed with standard loads, and suppressed with subsonic loads using the PSA 5.7 Rock handgun. It highlights the significant noise reduction achieved with a suppressor and demonstrates the effectiveness of subsonic ammunition in a suppressed firearm, noting the heat generated by rapid firing.

Quick Summary

When comparing 5.7x28mm ammunition, suppressed firing dramatically reduces noise and muzzle flash compared to unsuppressed. Subsonic loads, like Fiocchi 62 grain Range Dynamics, offer the quietest suppressed experience. Rapid firing with a suppressor generates significant heat, requiring cooling periods.

Frequently Asked Questions

What is the main difference between suppressed and unsuppressed 5.7x28mm firing?

The primary difference is the significant reduction in noise and muzzle flash when firing 5.7x28mm ammunition through a suppressor. This makes shooting much more comfortable and reduces the audible report considerably.

How does subsonic 5.7x28mm ammunition perform when suppressed?

Subsonic 5.7x28mm ammunition, like the Fiocchi 62 grain Range Dynamics, offers an even quieter shooting experience when suppressed compared to standard supersonic loads. It minimizes the sonic crack, making it ideal for stealthy operations or reducing noise pollution.

What firearm was used to test the 5.7x28mm ammunition types?

The video utilizes the Palmetto State Armory (PSA) 5.7 Rock handgun for testing. This pistol is equipped with a 5.2-inch threaded barrel, making it compatible with suppressors.

What should be considered after rapid firing a suppressed firearm?

After rapid firing a suppressed firearm, it's important to be aware of the significant heat buildup in the suppressor. Visible smoke indicates high temperatures, and allowing the suppressor to cool down is recommended to prevent damage and ensure safety.
