This video compares dedicated 9mm suppressors against multi-caliber .45 ACP suppressors, highlighting performance differences. The Gemtech GM-9 and SilencerCo Osprey 45 are tested on 9mm hosts. The Osprey 45, despite being a .45 caliber can, proved significantly quieter for 9mm than the dedicated GM-9, demonstrating the benefits of larger internal volume for sound suppression.

Quick Summary

A multi-caliber .45 ACP suppressor (SilencerCo Osprey 45) proved audibly quieter on a 9mm pistol than a dedicated 9mm suppressor (Gemtech GM-9). This highlights how larger internal volume and design can significantly impact sound suppression effectiveness, even when not strictly caliber-matched.

Frequently Asked Questions

Is a .45 caliber suppressor quieter on a 9mm pistol than a dedicated 9mm suppressor?

Yes, in this test, the larger volume SilencerCo Osprey 45 (.45 ACP) was audibly quieter on a 9mm host than the dedicated Gemtech GM-9 (9mm). This suggests that internal volume and design can be more critical for sound reduction than just caliber matching.

What is a Nielsen device and why is it important for pistol suppressors?

A Nielsen device, also known as a booster, is crucial for many pistol suppressors used on firearms with tilting barrels. It compensates for the added weight of the suppressor, allowing the firearm's action to cycle correctly by using gas pressure to push the barrel forward.

What are the advantages of a multi-caliber suppressor?

Multi-caliber suppressors offer greater versatility, allowing them to be used on firearms chambered in various calibers. This is particularly advantageous given the NFA's tax stamp system, as one stamp covers one suppressor, making a versatile option more cost-effective in the long run.

Can a suppressor block my pistol's iron sights?

Yes, suppressors, especially larger ones or those with thicker bodies, can partially or fully obstruct the view of standard iron sights. This can affect your ability to acquire a proper sight picture and may necessitate the use of taller sights or optics.
